I've searched on the forums to try and sort out this problem but I can't, I've noticed alot of people are getting problems connecting to the database because there username or database name is too long. The maximum characters I see other people say is 15 or 16 I'm not sure, my username and database name alone is 15-16 already. I'm stuck, please help?
