I have my web site which I published on Winhost.com I use forms athentication on my web site. It works fine when I run it on localhost or on the servers of another hosting company but here it does not work at all and I don't understand why. Previously I used to have this kind of problem when publishing the web sites but I resolved it by adding machineKey section to my web.config. Now I already have this marchineKey section but the problem still remains... Although the problem is a bit different from what I used to have: It's not that I get logged in for 1 min and then it logs me off. For some reason it's like I'm not logged at all, even for 1 min! Although the password, etc is 100% correct and I can log in when I run this app on my localhost using the database of Winhost. Any help in resolving this issue is welcome. Thanks in advance.
