This happened when registering

1-Yes
2-Yes.

Hmm, Kyttias, would you mind if I take a look at your config_forums.php? I think there may be something there.

*shrug* Sure, if you think it'll help.

PHP Code:

<?php
//Mysidia Adoptables Site Configuration File

//Forum Integration Info: MyBB
$mybbenabled = 1; // 0 = disabled, 1 = enabled
#
#
#
#
$mybbpath = '/forum';
$mybbprefix = 'mybb_'; // This is the default setting as you install MyBB forum, feel free changing it if you have a different prefix
$mybbremember = -1;          
?>

I hid my mysql database info for the purposes of copy-pasting it up here, replacing it with #. (However, these four entries should match what you have in your normal config exactly.)

Er, do you also mind if I take a look at your functions_forums.php? Sorry about bothering you!

Well you shouldn't need to change anything in function_forums.php, it is a library file that does not have any configuration variables for you to set. I think to fix forum integration for you, you will need to change the auto increment ID for users table in both adoptables and forum database. I can do it for you if you don't know how to, then you can test it again and lemme know if it works for new registration.

Okay! It's worth trying.

Actually @Kyttias I double checked logging into my forum directly and found out that it doesn't work! I thought I did before...

What's the problem and is there a fix for this?

EDIT:
Changes made were changed back so the problem was there all along.
