I have had a misshap during upgrade to 2.4 this morning. I attempted an upgrade via Softaculous but received error messages so I restored the back-up taken before running the upgrade. I now get the Zend_Session Exception pasted further down whenI try to login to the admin control panel. The site itself works OK, it is just the admin.
I have tried having my full site restored from back-ups taken this morning and on Wednesday morning but I'm still receiving the error, so have gone back to this morning's backup.
Can anyone help me to figure out how to recover my Omeka site so that I can login to the backend again please?
