Figure this out for me. I found this statement on a blog site;
“In your WordPress admin, go to Pages > Add New, and create the two pages as you normally would. Call one Registration and the Other Activation”
I created both blank pages (notice it is Registration, not Register) — change the settings page to point to them and MAGIC — I now that a Registration button, point to the Registration page, which appears to work
I am currently trying to figure out how create registration and activation pages. This is apparently not a new issue — I still wading through the support thread. https://buddypress.org/support/topic/registration-and-activation-pages-missing/
It talks about switching to the bp theme — which isn’t listed as a selectable theme.
I have found the files under bp-themes/bp-default — I just need to discover what to do with them. (more reading ahead)
