Happened to me again on my mobile device, the forums were also failing to load. Got different error messages, initially thought the forums were down but apparently they weren't.
Mainly only when I post; but when it happens I cannot refresh any forum page---but I have internet access since every time I check other sites and they work.Seams to be only when you post right? and only some of the time, I am looking into it.
I did what Castellon suggested, too (I logged out of this Macbook after I read his massage but the system logged me out again when I posted the above message). I only had lag once in the Guess the Skyline thread so far.I luckily haven't been logged out since around noon today---though I did voluntarily log out sometime in the afternoon as proposed by Castellon after the lag fix had been made. Since I made that logout I haven't really had any lag. And what I have had hasn't really been that serious.
Due to your probation status. Those permissions were updated when I redid the ratings permisions.
