thanks for the reply.
Indeed, adding that CSS sniplet now shows the disc bullet on the post/page.
However, the indent of the list item does still not work.
Have a look at http://gfcev.de/anforderungen-sichtweisen-kalender-2017/
The bullets have a negative indent and the text of the list item has no ident.
(Further down the side, you see that ordered list works fine.)
You can see the same issue in the widgets.
bullets have a negative indent, but the list item text is correctly idented.
Any further good addvice how to fix the ident?
Thanks and best regards
