  • Please disable module Apptrian_ImageOptimizer for a while and check if admin is working or not. If yes, then you need to debug into Apptrian_ImageOptimizer module.

  • My next move would be to look at line 724 of the file that is causing the error and edit it as necessary to avoid whatever the problem is. No need to "fix" anything, since whatever the problem is doesn't seem like it is needed just to view the admin. You can also try renaming that module's etc/admin/system.xml to etc/admin/system.xml.off and clear the cache from the command line. That might temporarily stop it from blocking the rest of the configurations.
