Error writing to readonly database

[Hardy]

Expected Behaviour:

In the query list, a click on 'Blacklist' shall block this domain in future.

Actual Behaviour:

By clicking on 'Blacklist' a message box appears with this content: " While executing: attempt to write a readonly database
Added 0 out of 1 domains"

I tried this: https://discourse.pi-hole.net/t/whitelist-attempt-to-write-a-readonly-database
/34055

and this: [Solved] While executing: attempt to write a readonly database error - #4 by deHakkelaar

Nothing helps.
