Hello! I got a "Zend_Session_Exception error similar to here: "Zend_Session_Exception"
I was quite certain my hosting company upgraded PHP, and since there was no way to go back a version, I decided to upgrade Omeka to 2.8.
I followed the instructions (https://omeka.org/classic/docs/Installation/Upgrading/). However, I could not disable plugins because of the Zend error. So, I replaced all the files (except the “files” folder and db.ini) with the new version, but I could not disable plugins.
While the Zend error is gone, now my site says “Public site is unavailable until the upgrade completes”.
Should I run the installer? Go back to the previous version? Any advice appreciated.
