Looks like the calendar app does not properly work together with your server installation.

Please upgrade our server to ownCloud 10 and get a properly working calendar app from the marketplace.

ownCloud 8.2 is end of live and no longer supported

Would it be possible for now to just get the webfront working again? Or do you think that upgrading will restore webfront funtionality?

By the way, I've tried disabling calendar app from CLI with no luck. I get err "PHP Fatal error: Class 'OC_Search' not found in /var/www/html/owncloud/apps/calendar/appinfo/app.php on line 39".

Try to remove /var/www/html/owncloud/apps/calendar completely - well actually move might be better just in case we need to restore it ....

Thank you so much. That did the trick. I can now focus on upgrading OC.
