Evo Blue and navigation issues

[ahoogerhuis]

We've just migrated off a very old OpenBB installation on to vBulletin and are getting to grips with a new system. We are running on the Evo Blue (fluid) style and thinks this looks all snazzy and nice, but we have one bug that most users noted since it is very different from how OpenBB behaved:

When using backspace to navigate back from a thread, the thread index still shows the thread as unread. A quick question to the vBulletin suggested tuning on the no-cache headers in the options panel, and it has some effect.

Now backspace navigation works on some version of IE7 but not on any version of Firefox 2.0.0.x. Can this issue be realted to how the theme is built?

Thanks in advance for any help.

Its the way vBulletin works, not a style problem. To mark forum read you should visit that forum after reading thread.

Just to close this one off, the reason is found, and it's a vBulletin issue.

A bit of comparing with OpenBB (the old software) and vBulletin and wireshark we found that even if vB is set to send "no-cache" headers, it isn't asking the client to revalidate, this is for some reason commented out (include/functions.php, line 3640-3641). Adding these back in makes backspace navigation work wonders.
