I just tested this on 2 different dnn 9 installations and the result is the same, an empty message.
I think this is a bug (as in the regex should not fail this address and the resource key might be missing).

I just tried that email on a local site and get this key RESX:RegistrationInvalidEmailUsed.Text After digging around some more, I have created this issue: https://github.com/dnnsof...Platform/issues/6077 many of those errors are missing the localized text.

The Regex for emails is in Security / Member Accounts / Registration Settings I feel like pasting regext here might be a pain for formatting. But if you google or use ChatGPT there are great resources out there for email regex. The main issue with the out of box one is that it limits the domain part to 9 characters and "foundation" has 10.

Daniel, I found this in the log folder for file "2024.06.19.log.resources":

2024-06-19 18:13:09.933-07:00 [win5195][D:3][T:40][ERROR] Dnn.PersonaBar.Users.Services.UsersController - System.Exception

@Marco: Security > Member Accounts > Registration Settings > Email Address Validation, replace value with:

Great job all on isolating a couple of potential issues! Teamwork makes the dream work (as some...ahem...former???...DNN community member once said). #thanksclint

This is the reason why I'm only using DNN! you guys rock! the community itself rocks! a BIG THANKS to you all! 

Thanks Timo for the regex code and thanks Daniel for looking at the key, I was going to do this at night since I was outside visiting a client.

Thanks again to you all for your time and for helping me figuring this thing out!

BTW, Timo the regex worked like a charm, thanks!

Yay!
