IE8 problem

can someone help me figure out what is wrong with the menu at www.mychemistrytutor.com/forums in IE8

the main site www.mychemistrytutor.com works fine

 

Something to try would be adding an ID to the table that holds the information, then setting a defined width in the CSS.

 

the width is defined in an ID
#nav it is at the bottom of the css

 

The issue you're having is due to this segment of your code:

ul.links li  {
  display: inline-block;
line-height: 1em;
  margin: 0 1em 0 0;
  padding: 0;
  color: #ffffff;
  text-transform: uppercase;

}

Code (markup):

"display:inline-block;" isn't supported in IE7 but is in IE8. When I opened your webpage in IE8, it displayed fine. Then, I decided to try running compatibility mode (IE7 Emulation) within IE8, and the issue appeared.

What you will probably need to do is change it to "display:inline;" or take advantage of floats and clearing.
