@ChristineWk @BennoMath @dautrich Have you also tested that an email address without underscore still works?

Am asking because that part is missing in the testing instructions. But it should always be tested that nothing is broken by a fix, not only that the issue is fixed.

This just in general, I don’t expect any issues.

@ChristineWk Thanks for checking. That’s sufficient for me.

Thank you everyone for testing this PR.

@richard67 I also successfully checked with an email address without an underscore, with the PR code applied.

[BennoMath]

@richard67 Yes, successfully tested also with an email address without underscore.
