How to solve my space sign in page problem?

This can happen if you have some virus in your computer as this happento me as well when I had a computer virus. I had to get rid of the virus to getit to work right again, and had to change my yahoo password altogether whichwas a pain because I’ve had yahoo for like 6 years and couldn't remember someof my answers to the questions it was asking me. And the second thingyou can do is to enter your MySpace url in the address bar andsee if your profile is still there. Sometimes it gets deleted and this problemcan happen. If you have changed your security setting or have updated your browser,then this too could have disabled your logins. Often you'll get awarning, saying "Do you want to allow this site?" etc. this happens alot if your computer is shared among other people.
