I’m running Ultimate member WP plugin 2.0.29.
My web server is using NIGIX and Varnish cache, login should’ve been excluded but I could be wrong. I do have CloudFlare as well. For testing, I’ve disabled CloudFlare (put in dev. mode), disabled Vanish caching and cleared all caches on the server and cloud. I cleared cache on my browser as well. Issue still persists.
At this point I’m scratching my head. I am happy to provide Admin credential via PM for you to look at it if that is okay. I love the Ultimate member plugin, and am planning to become a paid customer once this issue is resolved.
