Looks like WCFM is one of the worst multivendor plugins with the worst support provided even after purchasing the ultimate version of the plugin I didnt get any useful support from them.
I didnt rate them 5 stars!!!
If I rate WHMCS-Bridge I will give it -100
Ricardo, did you try their support to reply?
Try to install the plugin and open a ticket with them than return back and reply
If the solution to install the Pro version then they should mention that the free version is available with bugs and no support so please install the Pro version (^_^)
Dear Sir
I am facing the same issue.
I can see that the issue is solved at your site. Can you advice me how did you solve it?
