WCFM is very, very good :D

It’s one of my favourite plugins that saves so much time – it might not have the most modern appearance but that doesn’t particularly matter because you can redesign the frontend yourself with customisations or custom code, so crucially the core functionalities and options are what matter here. I would highly recommend WCFM. I’ve found that some issues were due to firewalls like Wordfence so you’ve gotta be careful that some user actions don’t get blocked, which has been the issue for some error messages, but you can whitelist the WCFM actions if you know what’s causing a safety blockage via a firewall.
