Here is the mistake I did. I went to admin screen >> options and the URI for the blog header was globalintegra.com/blog and I changed it to http://www.globalintegra.com/blog
Since I made this change the background has disappeared and I am unable to login to the login screen, when I go to the blog site it is always logged on. Also none of the other links to manage, write, etc. works. They all give an error message when clicked upon.
Any help to fix this problem is appreciated very much.
