<solved> Problem after upgrade to 1.51

[Deblus]

I have just upgraded from 1.31 to 1.51 by ftp following the instructions in the wiki, my host meets all the minimum requirements

The upgrade/install proceeded normally with no errors

When I view my site www.deblus.com.au the home page appears as normal (desired) width but all other pages appear approx twice the desired width.

Tidy html validator shows an error that "html cache is empty" this error was not there prior to the upgrade only some ,minor warnings

I believe the problem is in the stylesheet "top simple plus two columns" but I cannot find it, the minimum and maximum page sizes are as they have always been set

I am viewing using Firefox 3.05, the same problem occurs using IE7 with the menus screwed up a bit due to the extra width of the screen

I have searched the installation and setup topics but cannot find any reference to this problem

Does anyone have any suggestions please

They have 2 style sheets that are almost the same, the second one that is giving problem is Deblus:Top Menu + 2 columns...

#pagewrapper has...
max-width: 200em; /* IE wont understand these, so we will use javascript magick */
  min-width: 160em;
