When I try to create invoices, I get this message I have created several items in this section of ISPConfig and still get the same message. Do I have to log out and then log back in to ISPConfig and try again? I searched the forum and found that the invoices are linked to the database table isp_fakt_rechnung. So I checked my database table and that table appears in the database just fine, but of course there are no records or items in that table. How can I fix this?
