Critical error when sending to translation

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

Problem:
The site shows a critical error when sending a page to translation.
Solution:
If you're experiencing a critical error when sending a page to translation, we recommend you check if the "Multibyte String" PHP extension is enabled on your server. This extension is necessary for the WPML plugin to function correctly. You can find the minimum requirements for WPML here: https://wpml.org/home/minimum-requirements/.

Please contact your hosting support and request that they enable the "Multibyte String" PHP extension. For more information about this extension, visit: https://www.php.net/manual/en/book.mbstring.php.

After the extension is enabled, the error should no longer occur.

Please note that this solution might be irrelevant if it's outdated or not applicable to your case. If after checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins, the problem persists, we highly recommend you open a new support ticket. If you need further assistance, please contact us in the WPML support forum.

Lauren Supporter Languages: English (English ) Timezone: America/New_York (GMT-05:00)	Once you have the file management plugin installed, please enable the debug log and see if there are any errors we can locate. To enable it, open your wp-config.php file and look for define('WP_DEBUG', false); Change it to: define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false ); In this case the errors will be saved to a debug.log log file inside the /wp-content/directory. The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it. If you open wp-config.php and that define statement is not there, you can add it right before this line: /* That's all, stop editing! Happy blogging. / Please note that you’ll see everything, not only related to our Plugins. This will most likely include messages from other plugins, your theme, and sometimes even WordPress core. The messages appear all over the place. Sometimes they appear right on top, but they can also appear in the middle of the page. DOC: https://codex.wordpress.org/Debugging_in_WordPress After enabling the debug mode, please try to replicate the issue. Navigate to the page where the error message being displayed.* The errors will be either displayed on the screen or logged in the debug.log log file inside the /wp-content/directory. Paste the latest lines here. No need to paste the entire log file, just 50 lines or so will do. Please censor any sensitive information.

Lauren Supporter Languages: English (English ) Timezone: America/New_York (GMT-05:00)	That does not look like a full error, can you share a link to the debug log, or a copy of it? You can upload it to Google Drive or Drop box and share the link here. If no fatal errors are showing in the debug log, then the next thing to test will be minimal settings, meaning only WPML active with a default theme, and test to see if the same issue is happening. Do you have a staging site where we would be able to test that? If not, I can set one up and you can migrate your site there.

Here is some information about it: hidden link Once this is enabled, the error should be resolved.
