Today when browsing around when I go into a thread I then use the back feature to go up to the forum. Well now it is not working because the browser history is filled up with facebook connect history. Probably some new feature of VB gone awry...
I've noticed the forward button hasn't worked in quite some time ...IE, this site only. As you go back, it brightens up for a second and back to shaded, like you never went anywhere.
With almost 30,000 people online a day and no one else having an issue I would say there is a problem with your browser.
Seeing the exact same behavior here.I can fix it by logging out of facebook. It is the facebook connect feature. The reason it probably hits me and very few other people is that I have facebook set to always use https. So, the facebook connect does the http then the https (as you can see by the screen shot I posted above). The script does not back out properly. It started when the last update was done. Probably a vbulletin bug that may eventually be fixed.
