Pro Sites Incompatible with Gravity Forms Stripe Plugin.

When Stripe is enabled, I get this error message:

Fatal error: Class 'Stripe_Account' not found in /home/nickvs/public_html/wp-content/plugins/gravity-forms-stripe/stripe.php on line 153

It seems that Pro Sites uses a Class called Stripe Account - and is looking for it everywhere on the site.

Will Gladly Give ftp access if you wish to peek
