Hello,
1) f4afcea6******* code used for the https://bf.aaampm.com/ 72b28a7b***** code used for the https://dooeat.co.uk/multi/ dfbb8ecd***** code used for the https://aaampm.com/manx/ and https://aaampm.com/rr-new/ (that is not allowed by the way). So, we don’t see any free licenses.
2) Update from 6.x to 8.x: a) Did you make any changes in the child theme? b) Did you create a header using header builder or use one of the built-in headers of the 6.x version?
Regards
