[1.8] Report Button not working with the forums that have template prefix

[Hamster24]

Hi
i upgraded to 1.8 yesterday.
when i realised spamalyzer is not working properly.
i started to make sure that people can report posts.

report post window pops up fine on all forums without the template prefix.
but in forums where i have custom templates the nothing happens when i click the report button.

Any idea why is that happening.

P.S. Rate/ Rep window is popping up fine.
