[Resolved] wp_installer_settings on autoload maxing out an causing 502 errors on site

Problem:
The client is experiencing 502 bad gateway errors on their site. The hosting provider identified that the 'wp_installer_settings' from wpml-string-translation is maxing out the autoload options, contributing significantly to the issue. The client is considering turning the autoload to OFF for 'wp_installer_settings' and 'wpml_strings_need_links_fixed'.
Solution:
We advised the client against disabling the autoload for 'wp_installer_settings' and 'wpml_strings_need_links_fixed' as it is not recommended. Instead, we suggested the following steps to diagnose and potentially resolve the issue:
1. Create a full site backup.
2. Update any outdated plugins or themes.
3. Flush any cache memory.
4. Activate WordPress debug mode as described in this guide.
5. Deactivate all plugins, including WPML ones, and activate a default WordPress theme like Twenty Twenty.
6. Reactivate the WPML plugins and then activate the theme and other plugins one by one to identify the culprit.
7. Check for any fatal errors in the debug.log file within the wp-content folder.
Additionally, we informed the client that the next WPML version (v4.9) will have a much smaller 'wp_installer_settings', although there is no estimated time of arrival for this update.
