Hi Philip,
I looked through our forums and internal tickets and did not see any issues related to PMP. However, that does not necessarily mean there aren’t any. We code all of our plugins according to WordPress best practices, so they should work well with other plugins that do the same. Issues do pop up though, which is why it’s always best to test them out in a development environment before implementing them in your live site.
I hope that helps, and please let us know if you have any other questions!
Thanks,
Brendan
