If there is a solution to this elsewhere that anyone knows of, please reply with a link.
The last time I viewed my Blog, it was all visible and easy to read. Now, it takes up the entire screen in Safari and the header gets cut off and the sidebar is cut off. I used to be able to see the metalic dark grey background on either side of the content. Now the content takes up the whole screen. 'm cleaning up the content, but haven't changed any php or css.
I did change my domain name and transferred the hosting to the new domain. The WordPress files are still intact on the FTP and I changed the domain and site address in the Settings from the Dashboard, so this shouldn't affect the display.
