Every iPhone user who tries to create an account gets errors that prevent them from completing their account. This happened on a Windows server as well as Ubuntu 22.04.01 LTS server with the latest J3 and JomSocial3 versions. No other errors on my site and no errors with JomSocial but every single iPhone user who has tried cannot create an account. Because of that, plus many other bugs, restrictions and problems, I'm working on trashing JomSocial completely.
