Problem solved:

I discovered that my server was using PHP 5.2.17
I asked them to install 5.6. They did, and activation of the plugin was successful.

I get the same error, but slightly different trigger.
I’m new to All-in-one event calendar. I’ve seen it in action and decided to add it to my WP site (self-hosted). I downloaded it, and installed it. Apparently OK.

However, when I tried to activate it, I got the same error as jonmckdenver reported above.

I don’t know which PHP version my host is running. How do I find that out?

My host is HostGator.
