Fatal PHP error while editing certain extensions

So, certain extensions when trying to be edited (when you hit save before you have the red "Apply" button) drop you to a blank white page. If you reload the changes aren't saved. I searched as best I could and found nothing on the web about this error I found: #tail -f /var/log/httpd/messages [error] [client ###.###.###.###] PHP Fatal error: Access to undeclared static property: endpoint_aastra_base::$modules_path in /var/www/html/admin/modules/endpointman/includes/timezone.inc on line 0, referer: http://pbx.####.local/admin/config.php?type=&display=extensions&extdisplay=### Obviously IP/extension # show correctly I just edited out for the sake of editing it out. Any advice is greatly appreciated, the only way I found around this was deleting/recreating a problem extension but this is really not ideal behavior/fix. Thank you for reading!

Oh crap and I missed the closing code tag and screwed it up. Hahaha… ohboy.

Remove/Uninstall Endpoint Manager.

So an uninstall/reinstall? Do you know what may have caused this? Not sure if it was you who fixed my original post but thanks!

Uninstall and if you want reinstall and yes I modified your post.

Thanks for the quick reply!
