I cannot add anything to blacklist : domain, regex, wildcard.
it gives me this error :

It works from pihole -b command line.
I can actually delete it afterwards from web int.

Hi,
Pihole 5 is still in beta status and support will be added with DietPi v6.29.
For time being you can use this workaround
