Could you report this issues using support form (Contact Us -> Problems with website and user accounts)?
Please include following:
- does this error affect only forums?
- what time does this error appear?
- how many times a day?
- you location
- is it ok right now (Mar 12)?
Or simply send me a PM...
As this reply quoted me, I assume this was directed at me? Well, I was mostly offline yesterday (March 12), so let me see whether this occurs again or not today (March 13), and if it does I'll use the support form. Thanks.
