System Config Page fails to save

[Christopher Johnson]

Hello,

(self-hosted with SVN version)

Since version 10.6 we have had a persistent issue where the System Configuration page will not save the chnages. [/pages/admin/admin_system_config.php], but as these options are normally setup and left, it hasnt causes masses of issues.

We have tried replacing the file from the repository, we have tried svn Diff to see whats changed, we have tried rebooting server and various other things, so far with no luck.

We have upgraded the RS version to 11 to see if that helps, but still nothing.

The server is running: Apache/2.4.58 (Ubuntu)
MySQL: 8.0.45-0ubuntu0.24.04.1
PHP: 8.3.6

The only errors we have seen, is in the inspector:
Uncaught ReferenceError: AutoSaveConfigOption is not defined at HTMLInputElement.onfocusout (admin_system_config.php:1798:15)
admin_system_config.php:1816 Uncaught ReferenceError: AutoSaveConfigOption is not defined at HTMLInputElement.onfocusout (admin_system_config.php:1816:15)

This does look like the culprit, but when i follow the trail and make tweaks, it still fails. I've exhaused my definitive knowledge and would be heavily relying on AI or this group to assist.

Thanks in advance.
