Reseller can't modify limits
Don't know if the error appeared in 3.0.4x, too. This error occoured with my first reseller today.
He created a new customer and wanted to adjust the limits. By clicking on any field an alert message says: (in german) "Die hier eingestellten Werte werden ignoriert, wenn als Mastervorlage nicht -Custom- ausgewählt ist!"
There is no place where the reseller can select a template. Not the custom one and no other. And so the limits for my resellers customers are set to -1 by default ignoring the resellers own limits.
