Failed to create forum account

[Kyttias]

There are just two important details when it comes to integrating MyBB:

one: Your site can't have any members besides you, else the process gets really messy (how to deal with that).

two: The newest version of MyBB won't work. You'll either need to download MyBB v1.6 or tweak a few internal files so you stop getting the 'Failed to create forum account' error while trying to register someone (see here for details).

This is just one of those questions that keeps getting asked over and over so I wish a sticky would be made for it. *sigh*
