Could you please clarify what exactly is missing in the admin area? Are you seeing the “TablePress” entry in the admin menu? Are you seeing the tables on the “List of Tables”? Are you seeing the table content on the “Edit” screen of the tables?
ok, that sounds strange. If possible, I’d like to take a direct look at this on your site. Could you therefore please get in touch via email (the address is on https://tablepress.org/impressum/ )? That way, I can investigate this directly. Thanks!
