With the Wordpress 5.2.4 release, We notice the Swplug wordpress version was broken and we have decided to do a rewrite to fix issue noticed in the V.1, This will take significant amount of time as Swplug services are free , non custodian and do not charge a fee to download or its usage.
The WHMCS version is very much compatible with the current WHMCS build and works fine
SWPLUG WHMCS DEMO , To Download it click swplug WHMCS V1.2.
The Widget service also works fine and can be found here .
