Hello Antonio @antoiub
I am experiencing the same issue as Rolf @rolfkrueger had, namely with Complianz freshly installed the wizard reached the point “Cookiedatabase.org” is says “Something went wrong. Could not load field cookiedatabase_sync. Try again”. Also after reding this post I cleared the cache unfortunately has not resolved this issue for me. I tried the cache clearing a couple of times too. Is it possible the REST API has gone down again?
Thanks for reading, Sadie
