Does anyone know how to change the date format in viart. Somehow when it installed it shows dates as yyyy/mm/dd and I'd like to change this to mm/dd/yyyy

Go to your var_definition.php
The code should be something like this:
 
$datetime_edit_format = array("M", ".", "D", ".", "YY", " ", "H", ":", "mm");
 
Hope this helps
