I had it in also chrome, and didn't in firefox. However I went into chrome and deleted my cookies and it's fixed.
To be specific I cleared them, clicked logout, refreshed the page... then logged back in.
It went to the old tech 2 style. I set it to AZB V4, then went back to a thread that previously gave the error.
Now that thread and others are working fine in chrome.
So, anyone else who can see it, clear your cookies.
