I use WHMCS with Plesk only and after ordering the monthly subscription I discovered that it doesn't work together and unfortunately i have to disable my mothly subs. I will be surely back as soon as this module will support Plesk. I hope you will add this soon guys!
I actually went thru the whole installation process and tried debugging this thing because I saw in the WHMCS logs:
The Package Module type is wrong meaning its not cPanel, Direct Admin, Plesk, InterWorx nor ISPSystem. This Softaculous hook will only work with cPanel, Direct Admin, Plesk, InterWorx or ISPSystem module types
I am trying to get the auto install scripts to work with Plesk 11, but have the product module set to Plesk10 in WHMCS per instructions.
So, as I see in this thread, the Softaculous hook won't work in plesk but the error message says it will?
