I have just added the latest DNN forum to my site at www.mawhitfield.net and after adding 2 new forums and posting one entry to one and 2 entries to the other (which I subsequently deleted as they were test entries), I now get the errors below. This keeps occurring despite the fact that the error message says 'currently unavailable'?

I guess my first question is 'Has this been seen before and can be resolved easily?'. Is there someway to reset a forum or refresh it or from this point on, is the module corrupted (tables etc.)? If required, how would I de-install and subsequently re-install.

Errors...

Apologies Matthias. I did do a quick search but didn't understand the answer until now. This appear to have resolved the problem. Cheers. I will be a little more detailed next time.

If one of my users encounters the same problem, is there a quick way I can login as them. That is, should I ask for their password so I can carry out the same procedure or do I ask them to subscribe to all forums first and then re-start the application. This time round, the problem was with the HOST account so no problems me carrying out the procedure.

Thanks in advance for your help.

Cheers MARK.
