The redirect following an admin notice is incorrect on very old versions of BuddyPress, or on forks of BuddyPress that don't bother to merge upstream changes in order to remain compatible with freely available BuddyPress plugins. The specific problem in this case is that bp_get_group_permalink() has, for several years, accepted an int$group_id as a parameter, and BPGES (as well as the BP 12.0 polyfill functions recently introduced) leveraged this. See https://buddypress.trac.wordpress.org/ticket/6749. As a fix, I've added fallback support to the polyfill library: https://github.com/hard-g/buddypress-12.0-url-polyfills/commit/b09dc593f40c5b7163c1126377d991be62f0a9cf
