OK – after extensive testing here. mdocs 3.8.5 is the last version that works on my site. I tried versions after and upto latest and it does appear to be a cap/permission issue.
Testing has been done with only mdocs and user role editor activated. When I go to v 3.8.5.1 or higher I get the message “Sorry, you are not allowed to access this page.” when trying to access the mdocs admin panel (left that panel page open to see when things break). Works on 3.8.5, breaks at 3.8.5.1 and higher.
Role editor indicates cap of mdocs dashboard for versions up to 3.8.5, nothing for mdocs above that version. Not sure when it changed to mdocs_allow_upload but I have not changed admin permissions using Role editor – and from what I can tell (all other plugins deactivated), something is affecting the cap/permission on version 3.8.5.1 and higher other than plugin conflicts.
Would like t help get to the core issue here and have been testing on my staging site, if you want to take a look. I am leaving v 3.8.5 active there and will revert on my production site until we can find a root cause.
Thank you
