What is the best way to clean up errors that show up from modules that have been uninstalled in the past and no longer show up in the module loader to uninstall?
For example the following error comes up from Admin > Schedulers >
Fatal error: require_once(): Failed opening required 'custom/include/Google/GoogleHelper.php' (include_path='/var/www/vhosts/webworkzdigital.com/clients.webworkzdigital.com:/var/www/vhosts/webworkzdigital.com/clients.webworkzdigital.com/include/..:.:/opt/plesk/php/7.3/share/pear') in /var/www/vhosts/webworkzdigital.com/clients.webworkzdigital.com/custom/modules/Schedulers/Ext/ScheduledTasks/scheduledtasks.ext.php on line 7
This appears to be from a module uninstalled some time ago (RT GSync ). That module no longer shows up when we look at Admin > Module Loader., and there is no module listed with that name in /custom/modules
We are getting ready to do an upgrade and we are trying to clean up error messages.
Thanks in advance for any suggestions you can provide.
