Not WPML issue

Problem:
If you're experiencing critical errors when running your first translation on your site using Elementor, and all plugins are updated, the issue might be related to the PHP memory limit.
Solution:
We recommend increasing the PHP memory limit of your WordPress installation. The minimum requirement is 128M, but we suggest raising it to 512M. You can do this by adding the following code to the

wp-config.php

file in your WordPress installation's root folder:

/** Memory Limit */<br />define('WP_MEMORY_LIMIT', '512M');<br />define('WP_MAX_MEMORY_LIMIT', '512M');

Please ensure to add this code above the line:

/* That's all, stop editing! Happy blogging. */

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket for further assistance.
