Good Morning Steve,
I looked at your site and everything looked good. Then I saw that you got it back.
Anyway,
To change everything you will have to make the same changes to each section of your page.
I do not know if you are using a M0nster template or not but this would mean changing the widths of everything in Top Of Page, Left Column, Right Column, Messages Area, News Area, Bottom of Page, etc.
Through the Admin Panel I set the page position to "Center". I then use custom only in each of the other areas mentioned above. For example:
Top of page is set to 775.
Left Column is set to 200
Message area is set to 575
News Area is set to 575
Bottom of page is set to 775
You can look at my site if you would like. I have just redone everything...
My WebpageBy the way, I have done a little trick that helps me easily find problems on my page. I inserted a remark statement at the top of each section so when I view my source from a browser I can quickly scroll down to the area I am looking for. For example <!-- Top of Page --> or <!-- Left column -->. View my source and you can scroll down and see the settings for each of my areas.
Hope this helps.
Doug
