it's not clear when you say "IT DOESN'T UPLOAD THE BACKGROUND AND TITLE FILE FOR MY CUSTOME PAGE".
please consider that we never saw screen, and you should describe by the point of view of someone who is not there to look.

since you say the self-test reports it working well, it's 99.999% that it's not a network/router problem. The server is actually (read it "potentially") working, and the problem is somewhere else.

the easiest way to not receive such annoying complaints by other people is to type normally.
