Ok that makes sense, should have checked that. Thank you!
I’m using WordPress 3.0.1 (which is not the latest version, though I am being told that I don’t need an update).
I deleted another event plug-in, and it didn’t make a difference. I was able to create an event under the Events section, but I’m still getting the notice that I need to configure the plug-in. I can fill it out, but instead of a submit button at the bottom, I get the error message that @maypealta posted.
I’m getting the same error. I have the most recent version of WordPress (whatever the number is – my settings say I don’t need an update).
