Been having a bit of a problem the last few days where forum pages never fully load. The page content all seems to load, but the tab icon is still spinning around.
Firebug tells me it's because of this resource that isn't being loaded:
On an aside, I've also noticed that sometimes the whole site seems slow and sluggish, and very occasionally pages time out. This has only been happening since the new look/upgrade on the site.
Which browser are you using and have you tried a different one. My FF loads fine.
And from time to time, there have been system wide page loading issues... They generally clear up with in a matter of minutes.
Oddly, it's Fx on my system that is the one playing up. Just tried Chrome, IE, and Opera and it's fine there. I think it might just be that one file from intellitxt.com misbehaving for Fx :-/
Adblock fixed that loading problem for me.
