I would like to request temporary access (wp-admin and FTP) to your site to take better look at the issue. You will find the needed fields for this below the comment area when you log in to leave your next reply. The information you will enter is private which means only you and I can see and have access to it.
Our Debugging Procedures
I will be checking various settings in the backend to see if the issue can be resolved. Although I won't be making changes that affect the live site, it is still good practice to backup the site before providing us access. In the event that we do need to debug the site further, I will duplicate the site and work in a separate, local development environment to avoid affecting the live site.
- Please make a backup of site files and database before providing us access.
- If you do not see the wp-admin/FTP fields this means your post & website login details will be made PUBLIC. DO NOT post your website details unless you see the required wp-admin/FTP fields. If you do not, please ask me to enable the private box. The private box looks like this: hidden link
I agree that it seems like something is interuppting the sync. Please enable the debug log to see if there are any errors, and if you can install a File Management plugin, I'll be able to see the errors myself. if you have a staging site please test in minimal settings 9Only WPML and WooCommerce core plugins with a default theme) to see if the issue is still happening. If you don't have a staging stie, let me know and I can set one up for you.
Thanks I was able to access FTP but we aren't allowed to enable debug log without first getting permission. I enabled it and found the following error:
PHP Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the
woocommerce-group-attributes
domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the
init
action or later. Please see Debugging in WordPress for more information. (This message was added in version 6.7.0.) in /var/www/vhosts/droix.eu/httpdocs/wp-includes/functions.php on line 6114
Please make sure that you have updated all WooCommerce and WPML plugins and if it stil is not resolved, then we will need to test minimal settings to rule out a conflicting plugin or theme (WPML with only WooCommerce and a default theme). This is best tested on a staging site. If you don't have one available for this test, you can create one using something like WP Staging, or you can let me know and I get set one up and get a copy of your site there.
Your Twenty Twenty Five theme is out of date, plus you did not deactivate non WPML plugins. Please test that as well, and make sure the debug log is enabled and rerun the sync. Then check the logs and let me know if you are seeing any new errors.
I registered a new site key for your site after seeing some errors in the advanced translation error log. After that, I was able to complete the synchronization for products and variations in WPML -> Support -> Troubleshooting (in the clean up section). Please let me know if there is anything specific you see that is not synchronized.
If everything is showing as synced, you can create a new key in your own WPML account, as I will need to delete the key that I created since it's not in your account.
I started running the taxonomy sync and it starts, but the site timed me out before it could complete. I also noticed you have a very large amount of taxonomies/variations, and this could be part of the issue. Regarding the issue with syncing a large number of variations or taxonomies, it's likely that your server is hitting a limit on how many input variables it can handle at once — specifically the max_input_vars setting in PHP.
Please try the following:
1. Increase max_input_vars
This setting limits how many input fields PHP can process at once. The default is usually 1000, but for your setup, it should be a lot higher. Try 10000 or even higher.
You can increase it using one of the following methods (depending on your hosting environment):
php.ini
ini
Copy
max_input_vars = 5000
.htaccess
apache
Copy
php_value max_input_vars 5000
wp-config.php
(Only works if your server allows it)
php
Copy
@ini_set('max_input_vars', '5000');
Hosting Panel / Support
If you're unsure how to do this, your hosting provider can make the change for you.
You can confirm it’s working with a plugin like WP Server Info or by checking the output of phpinfo().
2. Other Important PHP Settings
Please also check and adjust these values:
Setting Recommended Value
max_execution_time 300
memory_limit 256M or higher
post_max_size 64M or higher
upload_max_filesize 64M or higher
These can affect large sync operations, especially with WooCommerce + WPML.
3. Use WPML Troubleshooting Tools
Go to WPML → Support → Troubleshooting and try these:
Clear the WPML cache
Fix terms count
Once you have increased max input vars, please let me know if you are able to run the sync in Taxonomy Translations.
I have managed to syncronise more taxonomies, however, I have a question:
It looks like after I syncronise all products -> I refresh the page and I press "Synchronize attributes and update product variations" -> The system just starts again from scratch, without no recollection of this being done previously. (eg: going through all the
I have tested on a test website, and that process automatically completes itself if I click on "Synchronize attributes and update product variations" after having done this previously.
So, something still could be wrong with the plugin?
