Currently, when saving settings in Moodle and an error occurs, only the generic message is displayed:

Some settings were not changed due to an error

This message is generated in admin/settings.php, using only get_string('errorwithsettings', 'admin');, without displaying the specific error details stored in $adminroot->errors.

This makes it difficult to identify and fix the problem, especially for administrators without programming knowledge.

Proposal

Modify the behavior so that the specific errors contained in $adminroot->errors are also displayed to the user. This would greatly facilitate debugging and improve the administration experience.

Affected version

Tested in Moodle 404, 405, and 500.
