Can't see forum with Firefox.

[Stefan118]

Please help.

Since I have upgraded my forum from 3.X to 4.1 users with firefox cant see the forum anymore.
I installed firefox myself, and I don't get it at all.
Safari works well!

This is a link to the forum: http://www.papegaaienforum.nl


And this is a screenshot of what they see in Firefox.

This screen appears in every style!
I have made a cleen style, didn't work.
Turned all the plugins off, didn't work.

What to do about this?

I see your forums just fine in firefox. I'm seeing a totally default style though - no bright blue like in the image.

Mmmm,
I can see it also...

What I had done was this:
I opened the page in Firefox, it dodn't show up correctly.
I created a new (clean style) in explorer and set it standard.
Refreshed the page in Firefox, but it seems the same.

After I had closed firefox and restarted it I could see it!

After all...
It was a mod I had done to place the header above the login.

Thank you anyway!
