After hours and hours of work getting everything set up and changing the WHMCS css files I thought I had finished. I even bought the single signup plugin.
But then, for no apparent reason, about half way through the ordering process the plugin stops working. Everything WHMCS disappears including the sidebar widgets. This happen just after you have chosen your domain.
On top of that the single signup plugin gives all sorts of errors and it seems the 2 plugin, made by the same people, do not work together because the versions are out of sync.
I don't really expect to get a response since there have not been too many in here but I felt the need to vent. What I thought was my saving grace turned out to be a total waste of time... and money.
By the way... I have been waiting about 3 days for a response to the query that I submitted to the Zingiri site.
