Well it really has me beat. I have posted a question on the SMF support forum. I really think the colours have nothing to do with it. It was just a coincidence. Choosing a colour just changes the forum stylesheet, not any source code. I was mucking around with some settings hence you getting logged off the forum at that time.
I'm trying to get advice on how to reset the post markers so that you will see all posts once again when you select "UNREAD". Please bear with me...
