[1.7.1] Division by zero error

Postby zanix » Wed Oct 25, 2006 1:58 pm

When a player has 0 exp, you may get 'Division by zero' errors on index.php and char.php

Exp isn't checked if it's zero and we all know what happens when you try to divide by 0...

Here is the manual fix
Or you can download the patched files
[1.7.1] exp 'Division by zero' error
NOTE: The Download includes the [1.7.1] Riding Skill Errors fix
