The following error appears when trying to change the Filter configuration:

Error output, so disabling automatic redirect.

Script /admin/settings.php?section=filtersettingwiris mutated the session after it was closed: $SESSION->cachestore_session: default_session-core/coursecat,default_session-core/courseeditorstate,default_session-core/navigation_expandcourse $SESSION->navcache
line 793 of /lib/classes/session/manager.php: call to debugging()
line 162 of /lib/classes/shutdown_manager.php: call to core\session\manager::check_mutated_closed_session()
line ? of unknownfile: call to core_shutdown_manager::shutdown_handler()

It stays then on an infinite loop, not letting me apply any change to the configuration.
The warning does not appear either.

Hi, the error isn't caused by this commit. I changed the filter to stable branch and still encountered this error.

It seems to be a native error in Moodle, and it's resolved in versions after 402.

I found info in this thread

https://tracker.moodle.org/browse/MDL-80735?focusedId=1058774&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-1058774
(I tried 403, and indeed, the error no longer occurs).
