Using 2.4.5 and event calendar 1.33, when I try to add an announcement I get a pop up box with this message: "The action 'admin' does not exist in class CMSMain".

I'm a dunce so have no idea where to start.

Thanks,
Bob

I went through the upgrade procedure again, and ran dev/build which changed two fields in the DB. I didn't make note of which fields exactly, but think they were a member field and the log in field. I have no idea how these got messed up. I had been trying to add the widget tab in my page.php.

Anyway I'm back to square one and happy about that.
