Second "page" of my forums uses different theme

[dvindiola]

I seem to have created a problem for my forum. I was testing some changes to the theme format/css and as a result now have one theme displaying for my main page and a different theme displayed when you click on a specific forum topic. Both of these themes do not show the images either.

Please advise how to fix and if possible how to avoid in the future.

Thank you much
