xthreads.php plugin file leaves forum in blank page

[Alan11]

I though PHP errors were set to be displayed publicly by default. Usually when there's a problem with the code, I'd see the PHP error displayed, what line it was, etc. It's just that this particular problem didn't result into a PHP error being displayed or logged. I tried setting it to report PHP errors via the xthreads.php file, but that didn't help either.

Reinstalling myBB on another directory to see if xThreads works fine on its own. If so, I'll then get the other plugins in one by one. I'll edit this post if I find a plugin that causes the error to repeat.

Update: Works fine on a new forum. Tried disabling everything but xThreads on the original forum, but it still failed.

Thank God, I finally see something:

Warning: Unexpected character in input: ''' (ASCII=39) state=1 in /inc/plugins/xthreads.php on line 733

Parse error: syntax error, unexpected $end in /inc/plugins/xthreads.php on line 733
