I’m really sorry about this Joe!
The issue here is a bit of weird one, so let me explain:
- We had an urgent security issue arise last Thursday, and so we worked hard to get an update out the door in under 48 hours from the original bug report.
- In that rush, the version of 4.0.5 that first went live on wordpress.org, for updates, had this fatal error in it. Terrible mistake!
- As soon as we noticed this, we pulled the original 4.0.5 update files.
- Then we fixed them and reuploaded them.
So basically, the first time we posted 4.0.5 it had this error. But it has now been fixed. When you updated on your site, you got the version with the error in it.
I’m really sorry about this Joe – it was a terrible mistake but from here, you should be able to basically delete the existing version of The Events Calendar off of your site, and then re-install the version 4.0.5 from here → https://wordpress.org/plugins/the-events-calendar/
Deleting the plugin will not erase event content, although backing up your site before doing this replacement is recommended if possible.
Let me know if you do this re-installation of the plugin and, if so, if it helps at all.
Thank you for your patience with this!
George
