Missveronica thank you!!!! That seems to have sorted it! 🙂
Thanks for your reply missveronica. I have tracked down a plugin that seems to have caused the issue. The plugin uses ajax for a specific (and critical) part of my site. The plugin allows you to switch ajax off for certain page loads, which I had done for all UM pages (or so I thought) Could you let me know all the pages that UM uses, specifically the one for updating profiles if possible. Kind regards
