Problem: If you're experiencing a fatal error on the WPML Theme & Plugin Localization page when Kadence Blocks is activated, it might be due to a conflict between WPML and Kadence Blocks. This issue is identified by a PHP fatal error related to unknown format specifiers in string placeholders within the WPML String Translation functionality. Solution: We recommend checking the WPML > String Translation section for strings that use placeholders like "%s comments". Ensure that placeholders like "%s" are correctly and identically translated across all languages. Additionally, the issue might be linked to a .po or .pot file on your server, which could contain errors. Review these files for any incorrect format specifiers or translation errors. For more details on similar issues, you can visit WPML Errata.
If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at WPML Known Issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If further assistance is needed, please open a new support ticket at WPML Support Forum.
I can not save the languages on the WPML > Languages menu.
Solution:
This must be a possible theme or plugin conflict. Here is how to check:
- IMPORTANT STEP! Create a backup of your website. Or better approach will be to test this on a copy/staging version of the website to avoid any disruption of a live website.
- Switch to the default theme such as "TwentyTwenty" by going to "WordPress Dashboard > Appearance > themes".
- Go to "WordPress Dashboard > Plugins" and deactivate all plugins except WPML and its add-ons.
- Check if you can still recreate the issue.
- If not, re-activate your plugins one by one and check the issue each time to find out the plugin that causes the problem.
