Hey,
Thanks for reaching out to us!
I apologize for the inconvenience you’re experiencing in using our plugins.
Looking at your plugin versions, our plugins are intended and guaranteed to work together at the same version numbers. In this case, we can guarantee that version 3.9.x of PRO and Community will work with 3.9.x version of core but we cannot guarantee that (and due to the nature of updates to our code, we would sometimes expect conflicts) 3.7 versions of Pro and Community will work with 3.9.x of our core plugin.
Let me know if this helps.
Thanks!
