Hi:
There is no ‘higher’ version. The paid add-ons all require that this version be installed and activated.
Unfortunately, it sounds like there’s a conflict here. The process to figure out where its coming from is a real pain though. But, there’s no other alternative.
The process is this:
1. Backup your system just in case.
2. Turn off all plugins besides awesome support. Does the issue go away? If not, switch your theme to a WP 2015/16/17 theme and try again.
3. If after turning off the plugins and testing again, the problem did go away, just turn on each plugin one by one, testing as you go until it fails again. Then the last plugin you turned on is the culprit.
I know its a pain but its the fastest way to figure out what’s getting in the way.
Thanks.
