I found that commenting out line 160 worked for me. Everything seems to be working now.
In my case, I do not have W3TC. Any other ideas what could be causing this?
I’m getting the same error message as bdub8888 when I try to go to “Installed Plugins” from the Dashboard.
I’m running WP 3.8.1 and didn’t have any issues until trying to update this All-in-One Event Calendar. I had version 1.10.9 of the plugin installed prior to this.
Now, I’m unable to access the Installed Plugins page to update anything else, deactivate, or delete any plugin that is already installed.
With that said, the calendar actually still works. I’m able to add and edit events like normal. I can also access the plugin Editor, so I’m guessing this is where I’d be able to fix this, but don’t know where to look.
I’d like to rollback the update if I could but not sure how I can. Any help would be greatly appreciated.
