[Resolved] Woo Product variations not synching continues

Hello,

I went to WPML > Support > Troubleshooting and used the taxonomy sync options for the post type "Products".

Then I cleared the cache in WP Rocket in all languages and now I see 837 products on the Finish category.

Let me know if further assistance will be needed.

Best regards
Andreas

I can still see 837 products here:

This issue seems to be Cache-related, and I can only suggest clearing the cache from time to time if the issue occurs.

This means, that this seems not to be an issue in the backend or the database. It seems to be only an issue with the view and WP Rocket is causing the view is not updated.

This can only be solved by clearing the cached files from WP Rocket.

I suggest you test if it is advisable to set the archive pages and shop page on the exception list of WP Rocket, so that it will not keep caching those pages.

Now, to escalate this issue, so that our team can take a closer look at the issue, I will need to try to recreate it.

Would you be able to provide the latest version of WP Rocket so that I can provide a test site on which we can run some tests?

Were you maybe able to identify a pattern, that the issue only occurs on specific products?

Can you currently recreate the issue by translating a specific product? If so, please name me an example.

According to the older ticket, the issues were solved if the translation was applied again, which is kind of odd, as the sync option for attributes will only sync global attributes that are declared at Products > Attributes.

Only custom attributes, that are created directly on the products, will be synced when translating a product again with the WPML Translation Editor - there is no other way to sync those,

You are using the plugin Object Cache Pro and we do have various known issues with this plugin:
https://wpml.org/errata/object-cache-pro-various-issues/

We would need you to provide a link to a sandbox for testing so we can try to recreate the issue.

Would it be possible for you to install Object Cache Pro on this sandbox?

Take note, that it might be difficult to recreate such an issue for any details about the affected products, translation workflow, and used settings of the site can count. This is why it might be helpful if you even try to replicate the issue yourself.

Hello,

You can install the following plugin and see the Object Cache Details including all available groups:

For further assistance about this topic please consult the Object Cache PRO Support.

Further, I can offer that try to migrate a copy of your website to our test server on Cloudways, in case you will be able to activate Object Cache PRO there for testing and the site is not too big.

Would this be possible? How big is the website?

Best regards
Andreas

Our own custom plugin does set the following groups to be excluded from cache:

wp_cache_add_non_persistent_groups( [
        'convert_url',
        'element_translations',
        'get_pages_adjust_ids',
        'get_user_admin_language',
        'translation_priority_relationships',
        'translationmanagement--get_translation_job_id',
        'wpml_cache_terms_per_lang',
        'wpml_endpoints_support',
        'wpml_pre_option_page',
        'wpml_register_string_filter',
        'wpml_register_string_filter--facetwp',
        'wpml_slug_translation_records--post',
        'wpml_slug_translation_records--taxonomy',
        'wpml_st_cache',
        'wpml_term_translation',
        'wpml_tm_blog_translators--has_translators',
        'wpml_wp_cache__group_keys',
] );

It uses the following WordPress function for this purpose:
https://developer.wordpress.org/reference/functions/wp_cache_add_non_persistent_groups/

The plugin can be downloaded here:

On your staging, the plugin seems not to work, as it might be having a conflict with another plugin:

The plugin WPML-Non-Persistent-Cache.php_/WPML Non-Persistent Cache.php has been deactivated due to an error: Plugin file does not exist.

You would need to handle the exclusion directly inside Object Cache PRO's config.

Also, at Settings > Object Cache PRO > Tools you will find an option that shows you all groups that are currently present in the cache. See screenshot.

I suggest you follow this guide and ask the Object Cache PRO support for assistance:

My apologies for the delay in answering, as Sundays and Mondays are my non-working days.

Your staging site appears to be very slow. I am not sure if this issue disappeared after I opened the Finish product translation on the WordPress Editor and clicked "Update" or if it disappeared because I ran all available updates on the site.

Do you have another example that occurred after implementing the suggested workaround?

Please also update Object Cache Pro, which is currently outdated on this site.
