Any help with this at all?

I'm no pro, but did you leave any tags open, or used any strange symbols? An symbol in the title maybe? (slash or quotation marks)

I tool out a symbol that wasnt recognised (the � sign) but i still got the same result...

Tom should have a look at this.

Does tutorial posting work for anyone else?

There have been new tutorials posted since your first post so I guess it does work.

Tom is pretty busy from what I understand, sorry it's taking some time.

Kyatric Nope, still wont post for me. Tried it in several places aswell, just tried again, still the Server URI Format error...

The issue I found out that causing the bug is if you've a line like this
