hi,
it seem a bug with domain wildcard on hotlink protection, step how to reproduce:
- add new website A with domainX.com
- add domain *.domainX.com into website A
- activate hotlink protection
- remove domain .*domainX.com from the website A
- add domain domainY.com into website A
the .domainX.com makes an error on vhost apache and i have to remove this manually
RewriteCond %{HTTP_REFERER} !.domainX.com [NC]
