Can you try re-installing the plugin? You will need to access your site via FTP and delete or rename the Event Espresso plugin folder to deactivate it. Then reinstall via the usual way (download from your account and Plugins > Add New >Upload).
Sorry for the delay… client craziness and shenanigans ensued following the post. Tried Dean’s suggestion to no avail. Did however find a weird workaround. Renamed the EE folder to deactivate it, went into the back of the site and correctly deactivated the calendar plugin. Renamed the EE folder to proper name and Activated it in back of the site. Then reactivated the calendar. Problem solved. For some weird reason it just would break every time we tried updating as long as the calendar plugin was active.
Just installed the latest EE update and tried activating while calendar still active with same results as before. Deactivated calendar, activated EE, then reactivated calendar, viola!
Very odd. I ran some offline tests and couldn’t replicate this. I’m glad you found a workaround, though I’d be interested in finding the root cause.
Have you tried re-installing the calendar addon?
