I also upgraded to plesk 7.6.1 and would know if is possible to upgrade to mailenable 1.96.
I downloaded the installation file from here http://www.mailenable.com/download.asp . May I simply proceed with upgrade?
Yes, these versions of products are supported by Plesk 7.6.1. However, you should have the old_passwords=1 directive in you my.ini in %plesk_dir%\databases\mysql\data
