I have recently installed the latest JSMF bridge (RC3_1) (using with Joomla 1.0.11)and have not had any difficulty while using the default SMF theme. Great piece of work and very straightforward install!
I installed a new SMF theme (orange-lt) to better integrate with my current site template (wrapped). When I go to the forum, it operates normally - but is now shifted far to the right - so that the left edge of the forum display starts at the end of the far right edge of the top/horizontal menus. I can login normally, but the whole forum is shifted to the right ...
I turned on debugging in the JSMF bridge, and this is a sample of what I got ...
Error loading buffer cache
Error loading headers cache
Error loading keywords cache
Error loading css cache
loading headers

All of this is on a local test site.
Is this an issue with the template? SMF theme? Bridge? Lousy luck?

Thanks for any help you might have ...
