I logged on as my tester self, made a post, replied to it and it all seemed hunky dorey, and I was off, in the knowledge that the Forum was working, albeit the previous version.
It wasn't until I picked up an email from 'Steve Zodiac' yesterday, stating that there was a problem with the forum, that I investigated. Lo and behold, there was indeed a problem.
So many, many apologies to the Members and visitors that frequent the forums. Hopefully it's back to normal now, and I'll try that update some time in the future.
Thanks Steve, much appreciated, and if anyone comes across anymore problems with the forums, please let me know.
Yours embarassingly
