I am wondering ;-) why you decided this hack is involved if in the code there is nowhere mentioned 'password' or 'pass' or 'sendpass' (as you may see this is the action's title which executes when you're trying to get the password, index.php?action=sendpass).
As you may see on minibbtest
, there is also such kind error of forbidden
. It could happen only in one case - when $genEmailDisable
setting of setup_options.php is not set or set to 0. That means any kind of using email functions is disabled on the server that way you also can't use the password reminder.
