MyBB Community Forums

For some reason when I try to log out of my account (it's an admin) I get a PHP error. I'm using the log out button at the top of the screen. No idea why it's doing it.
Running Mybb 1.6.12 with the Apart Night theme, and about 15 plugins.

I created a test account just in case someone wanted to reproduce the problem:
Username: test
Password: mybb

Disable Announcement plugin it's causing this issue!

Thanks for the response... I'm so stupid for not noticing the announcement plugin being mentioned in the error code..
Any way I can still have the plugin without it creating this issue?
