Question Cannot redeclare class smile

I'm getting an error on one of my forums with the latest 1.6 RC1 install.

Fatal error: Cannot redeclare class smile in /httpdocs/components/com_kunena/template/default/smile.class.php on line 31

I'm using the default template. I get the same result when trying to switch to the other template included with 1.6.

Only one forum out of 6 of our forums is exhibiting this behavior - the other ones you can enter them normally. Also, I can still display a post from within that forum successfully. I can't think of anything that's unusual about that forum other than it's our most active forum, so it might be triggering some call that the other ones aren't.

Any suggestions on how to resolve this issue or other things to try?

Thanks!

Uhh...completely spooky. It's working now with no changes on my end that I know of...

I'll post back if the error re-appears. :blink:

Do you have APC installed into your system? I've seen this kind of errors with APC after files get updated. Easiest way to fix this kind of issues is to restart Apache (not the most obvious fix, but could work next time).
