This is how it looks. Now with PHP version 7.3
The email is just blank and it is pretty strange. I has worked fine for at least 10 months now since I installed it, if not more. Clearing filters does nothing because I never set one. I did try anyway just for the sake of it. But it has no effect.
Maybe this happened when I changed to PHP 7.4…
I don’t know for certain. 
Kind regards
