[Resolved] Prices of some products are not updated and sorting by price is not consistent
This thread is resolved. Here is a description of the problem and solution.
Problem: You are trying to synchronize product translations on your site to ensure that the prices of products in the original language match those of the translated products. However, you are facing issues with some prices not being up to date and some being misordered when sorting by price on the translated product pages. Solution: 1. Ensure that "WooCommerce Multilingual & Multicurrency" is enabled. This should resolve the price issues for most products. 2. Navigate to WooCommerce > WooCommerce Multilingual & Multi-Currency > Products. 3. Filter the translation status to "Needs update". 4. Update the product translations now. Note: It appears that some products that need updates were never fully translated to 100%. The setting "Translatable use translation if available or fallback to default language" might be causing untranslated products to display in the default language. Regarding the ordering by price issue, it might be due to different market prices for each product, causing the second language to query the highest price available on the translated product instead of the lowest.
If this solution does not resolve your issue or seems outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If problems persist, please open a new support ticket.

<b>Background of the issue: </b>
I am trying to synchronize the product translations for my site (hidden link) and I would like the prices of the products in my original language to match the translated products. (hidden link)
As you can see by comparing these two pages: some prices are not up to date and some are misordered.
The problem is solved by updating the original product but the problem is that I have about 5000 products updated several times a day and this solution is not viable for my use.
<b>Symptoms: </b>
Some prices are not up to date and some are misordered when sorting by price on the translated product pages.
<b>Questions: </b>
How can I ensure that product prices are consistently updated across translations without manually updating each product?
Now, add this snippet to the end of the functions.php file of your theme and go to Products > All Products.
add_action( 'admin_init', 'save_all_products_on_products_page' );
function save_all_products_on_products_page() {
global $pagenow;
// Check if we're on the Products > All Products page
if ( $pagenow == 'edit.php' && isset($_GET['post_type']) && $_GET['post_type'] == 'product' ) {
// Get all the products
$args = array(
'post_type' => 'product',
'posts_per_page' => -1
);
$all_posts = get_posts( $args );
// Loop through all the posts and update them
foreach ( $all_posts as $single_post ) {
wp_update_post( $single_post );
}
add_action( 'admin_notices', 'bulk_save_products_notice' );
}
}
// Function to display an admin notice
function bulk_save_products_notice() {
?>
<div class="notice notice-success is-dismissible">
<p><?php _e( 'All products have been successfully updated.', 'textdomain' ); ?></p>
</div>
<?php
}
Now, remove the snippet again. This snippet should have saved all your products in all languages.
I think my server is not able to handle this type of request because I get an internal server error 500.
After investigating, it seems that it is the "min_price" and "max_price" in the "wp_wc_product_meta_lookup" table that causes the sorting problem.
In addition, I use the "content-egg" plugin that lists the best offers in different stores
for each product and since WCML locks the price fields this creates another price display problem if a user visits the translated product page before the original language one.
Disabling WCML solves all the problems but I don't know if I will really be able to continue without it because apparently I can't translate the attribute names without WCML.
Hoping to have been clear enough, I look forward to your help and advice.
Please try to connect to the server, open the wp-config.php and adjust the WP MEMORY LIMIT to 256M.
define( 'WP_MEMORY_LIMIT', '256M');
Now, try to run this slightly adjusted snippet:
add_action( 'admin_init', 'save_all_products_on_products_page' );
function save_all_products_on_products_page() {
global $pagenow;
// Check if we're on the Products > All Products page and if the action has already run
if ( $pagenow == 'edit.php' && isset($_GET['post_type']) && $_GET['post_type'] == 'product' && !isset($_GET['bulk_save_done']) ) {
// Get all the products
$args = array(
'post_type' => 'product',
'posts_per_page' => -1
);
$all_posts = get_posts( $args );
// Loop through all the posts and update them
foreach ( $all_posts as $single_post ) {
wp_update_post( $single_post );
}
// Add admin notice
add_action( 'admin_notices', 'bulk_save_products_notice' );
// Redirect to the same page with a flag to prevent rerunning
wp_redirect( add_query_arg( 'bulk_save_done', '1' ) );
exit;
}
}
// Function to display an admin notice
function bulk_save_products_notice() {
?>
<div class="notice notice-success is-dismissible">
<p><?php _e( 'All products have been successfully updated.', 'textdomain' ); ?></p>
</div>
<?php
}
As I told you, the website works fine without WCML so I'm definitely thinking of disabling it, the only problem is that I can no longer translate the product attributes name in "WPML > String translation" or in "WPML > Taxonomy translation".
Is it because I started translating these attributes using WCML or something else?
I would like to offer to have a closer look at the problem and request temporary access (wp-admin and FTP) to the website to investigate this issue further.
You can find the required fields below the comment section when you log in to leave the next reply. The information you provide is private, which means only you and I can see and access it.
IMPORTANT
Please be sure to make a backup copy of the website and database before allowing us access.
If you can't see the wp-admin / FTP fields, your post and website credentials are set as PUBLIC. DO NOT publish the data unless you see the required wp-admin / FTP fields.
I may have to install a plugin called "All In One WP Migration" to make a copy of the website where I can investigate the issue further.
However, I would also be very grateful if you could provide a staging site or copy of the website from your server yourself for this purpose. This step would only be required if the issue is replicable on such a staging site.
If you have any questions about creating such a staging site, you can consult your hosting provider. Just take note that WPML should be registered on this site again.
If you are unable to provide such a copy of the site for testing, please let me know on this ticket.

While reviewing the archive I see that the prices seem to be fine.
Take note again, that you always need to update the translation after editing the original product.
About the order:
To know why the order queries are not identical in both languages I need to run further tests. This could be an issue with the Rehub Parent Theme, or it could be caused in your Child Theme or it could even be that a third plugin is causing the issue.
I will be taking a copy of the site for running some tests and then get back to you.
Due to the high amount of product on your site I can not suggest using a script to update everything in bulk.
1) Make sure "WooCommerce Multilingual & Multicurrency" is enabled and this should already solve the price issues. At least it solved it for one of your provided examples, but I did not confirm them all.
2) Go to WooCommerce > WooCommerce Multilingual & Multi-Currency > Products.
3) Filter the translation status to "Needs update".
4) Update now the product translations
It seems like some of those products that currently need an update were actually never yet translated to 100%. There are only 326 translated French products.
The other products displayed in French are actually the original products, as you are using the setting "Translatable use translation if available or fallback to default language".
Are you not planing to translate all the products?
About the ordering by price issue:
- There might be an issue regarding the fact, that each product uses various prices for different markets. It seems like in this case the second language will query the highest price available on the translated product instead of the lowest.
I can offer a WPML test site on which we could try to recreate this issue for further escalation but I will need you to provide the theme and any necessary plugins in this case.
Indeed, I only translated 326 products because I wanted to fix these issues before continuing and as you noticed, due to the large amount of products on my site, I preferred to use the setting "Translatable use translation if available or fall back to default language" to allow the display of products that are not yet translated.
I disabled "WooCommerce Multilingual & Multicurrency" because all the problems come from the fact that it prevents the price of the translated product from updating itself.
Since I do not plan to use a second currency, I do not think it is really an issue.
The only remaining problem was the fact that I cannot translate the attribute labels without "WooCommerce Multilingual & Multicurrency" so I added a line in "product-attributes.php" using the hook filter "wpml_translate_single_string".
In conclusion, there are two things that I find totally disconcerting:
1. I find it disappointing that they don't give us the choice to ignore the price fields in "WooCommerce Multilingual & Multicurrency" especially since the setting exists but is locked for a reason that is beyond me.
2. The fact of being forced to use "WooCommerce Multilingual & Multicurrency" to translate the attribute labels when we can translate the attribute terms in "WPML > Taxonomy translation".
Thanks again for your help, maybe you could pass this information on to the relevant departments because I would be really surprised if I were the only one wanting to translate a price comparison website.
