Is it database or just the forum with the problem? If its the forum you could reinstall it and use the old database.

It's a database issue, though if I could have fixed it, it did need a forum software update in the near future.
By the way, you make it sound very easy...I've been trying to resolve it for 18 of the last 24 hours! The solutions I have been offered would involve significantly more time than I have available to work on this
ChileanLlama Would I be allowed to set up a similar forum on my webspace?
Thanks.
I have no objections - it was an independent forum - created for the early adopters (sadly most of them have moved on now) which grew over the years. Though I've not decided what I will do with "UKTrainz.co.uk" so I'm not letting you have the name/domain

In my own opinion, it would be better to look at other forums already in place for the UK and concentrate on them, traffic and discussion on UKTrainz was steadily reducing anyway - so I guess this has just brought forward the inevitable.
I have considered re-initialising the forum software, but it would mean starting from scratch. Given I'm no longer active in the Trainz world, I didn't think that was the best way forward.
Finally, I'm afraid I don't have email addresses for everyone at UKTrainz, apologies that I have been unable to contact people individually and that the absence of the forum and this thread will be the first they hear about it.
