Hi @babylon1999 ,
thanks for your response and the explanation – I’m getting to understand better bit by bit.
The host said, they could not help (except deactivating the security measures completely which is no serious option), because the server reacts correctly by triggering a 403 error since the htaccess forces to this. They said, the problem has to be solved within the WP/WC-configurations.
Any further ideas to solve it?
Thanks & best regards,
Fabian
