@ajgetmilk01 check once with AWPCP support. They might not have released any updates to support BP v12. You can also try it once with BP v11.4 to double-check at your development site.

@thinlizzie last stable version is v11.4, with classic features.

BP pages are moved to a Custom Post Type in BP v12
You can manage them directly from BP Options >> URLs

With BPv12, BP Classic can be used if you have other custom codes that are not ready with BPv12. Otherwise, you can use BP v12 without BP Classic.
