This happened once before when updating Nextcloud from 11 to 11.0.2 and now has happened again updating Nextcloud from 11.0.2 to 12. After performing update I can no longer access the Admin console. I can access everything else, but when I click on Admin, I receive the following message:
Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.
The resolution last time was to remove OnlyOffice. Did the same this time, but no joy. So wandering if its some other app causing Admin access not to function. Any help much appreciated. Thanks all!
