Cant Login to ACP
 

HI!
I made a copy of my online forum to my oflline private server for testing purposes and I cant login to the ACP.

I changed from http://www.mydomain.com to http://my.ip.add.ress/mysitename/www
I uploaded the tools.php and wanted to reset the cookie domain and it will say that my cookie domain is mydomain.com and even if I hit the reset link it wont change.
I edit the setings table bburl or something to point to my homeserver url and nothing happens.
Any suggestion?
Tnx!
