Ok, thanks, I have disabled it. Unfortunately, I am facing a big issue. Every time I try to create a translation, it will randomly overwrite the content of other posts with the default language :
1/ I translate post X from French to English
2/ It will overwrite the English content of post Y with French content
=> I had this issue 3 times this week... There should be a mismatch in the IDs. I don't understand what's going on, but it is problematic because I am losing content every time...
How can such an issue happen? I am running 4.7.6, so it should have been fixed. Maybe it is different. I can't understand how you can modify the site content automatically like this without worrying about what you are doing.
Then, go to Settings >> Permalinks, click Save Changes (no need to modify anything), and clear all types of caches. After that, please check if the issue still exists.
Therefore, please try it by adding to your wp-config.php file after taking a full site backup, and let us know if it helps.
Also, could you please check if the issue is reproducible with a new post or page?
If the problem persists, please share a screencast so we can have a better understanding of the bug. This will greatly help us in troubleshooting and our internal discussions.
Thank you for the updates. This is a workaround we have recommended in the past for a few clients who had similar issues while translating posts created using Page Builder. So, we would like to make sure it is giving you the expected results on your site as well.
Please note that each site is different due to the combination of plugins and theme being used. That is why it is always safe to take a full backup before updating WordPress, plugins, theme, or making any code changes.
Thank you for the updates. This requires further checking, so I have a couple of requests:
1) Please share the exact steps to reproduce the issue on your site. It would be very helpful if you could provide a screencast demonstrating the steps. This will assist us greatly with our internal communication and investigation.
2) Please fill in the private details fields after a full site backup. I would like to access the admin area of your site for further checks. For more information about our private information sharing policies, please refer to the links below:
This won't be possible to debug on site as this is a live site.
I usually edited a default language post and it seemed to overwrite the alternate language content.
