WPML can't run normally. There is an installation or server configuration problem

This thread is resolved. Here is a description of the problem and solution.

Problem:
After migrating a site, the client encountered an issue where WPML could not run normally due to an AJAX Error and a server configuration problem. Additionally, there was an inability to edit or see text in the editor, even though the AJAX Error was resolved after re-migrating.
Solution:
We recommended checking with the hosting provider regarding the AJAX Error as it is typically related to server issues. For the memory limit issue, which could also affect WPML's functionality, we advised increasing the WordPress memory limit. This can be done by adding the following lines in the

wp-config.php

file, right before the '/* That’s all, stop editing! Happy publishing. */' line:

define('WP_MAX_MEMORY_LIMIT', '256M');

define('WP_MEMORY_LIMIT', '128M');

After updating, the client should verify the new memory limit under WPML > Support > WordPress > Memory limit.
If these steps do not resolve the issues or if the solution seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that the latest versions of themes and plugins are installed. If problems persist, please open a new support ticket at WPML support forum.

Kor Supporter Languages: English (English ) Timezone: Asia/Singapore (GMT+08:00)	Thanks for contacting us. An Ajax Error is usually a server-related issue and could you try checking this with your hosting provider? Also, while checking the debug info, I see that the WordPress Memory Limit is below the requirements. The minimum requirements are 128M, but we do recommend 256M and the debug information of your site shows it set to 40M. Please check this link for more details https://wpml.org/home/minimum-requirements/. You can increase it by adding the following code in your wp-config.php file, right before the /* That’s all, stop editing! Happy publishing. */ line: define( 'WP_MAX_MEMORY_LIMIT', '256M' ); define( 'WP_MEMORY_LIMIT', '128M' ); After adding the code you can confirm that the memory was changed correctly from WPML > Support > WordPress > Memory limit.
