Conflicts with Ninja Forms > PayPal Express

As a quick fix, I installed a version of this plug-in from when it was still called WP User Avatars.

I have Ninja Forms, and the premium Ninja Forms PayPal Express plug-in installed on two of my sites, and (had) ProfilePress. After trying different resets of the NinjaForm plug-in, and testing a different theme, I came to the conclusion that it had to be a plug-in.

For some reason when this plug-in is activated and I try to collect a payment on a NinjaForms, the user is not sent to the PayPal page. It is beyond me why a ProfilePress would interfere with this. I only ever wanted the custom avatar functionality (and not the whole membership aspect), so reverting to an old copy of WP User Avatar and never clicking the update button will probably be my long term fix, but if you can figure out this conflict, that would be nice. I only recently updated some plug-ins on my websites… including ProfilePress, and that is when the PayPal Express stopped working, so it must be something with this current version of the plug-in.

I will report this issue to NinjaForms as well.
