Hi folks,

I've a problem. I copied a WordPress site to another domain on plesk and I keep getting kicked out of WordPress. When I log in it says I can't log in under wordpress.com in staging mode. Have any of you also had this problem? I used to use the clone function but I have the same problem with that.

What is the reason for the kicking out? How can I disable this staging mode? I want to use the copied site as a productive site, just with new content.

Thanks a lot in advance

Regards
