Hi
I realized that when you set a number minimum than the default (50) in the "Question minimum length" configuration it does not work.
The form is not sent until there are more than 50 characters.
I spoted the problem.
It is in the file: components/com_virtuemart/controllers/productdetails.php
line 62. If you modify the
$min = VmConfig::get('vm_asks_minimum_comment_length',50)+1;
to:
$min = VmConfig::get('vm_asks_minimum_comment_length')+1;
it works. That means that the VmConfig::get get its value from the 2nd parameter and not from the set setting.
