Hi @levymetal
Thanks for the bug report.
I’ve done some testing and it looks like WP is preventing the save_user action due to the error.
If you try to update any other core user info such as ‘Name’, the same issue occurs: New value is not saved.
I’m not sure I can do much for this on my end, seems like a security block from WP’s end.
Thanks again for the bug report, and I hope for now this doesn’t cause you project too much hassle.
Thanks
E
