Something similar was brought up in another post but I wanted to clarify a few specifics of the problem.
drupal 6.13 with marinelli 6x-2.95
after a successful (read: no errors) upgrade everything looked good here on my Firefox browser. I received a call from the client saying the site was looking bad on their IE system. I confirmed that it appeared drupal wasn't connecting to the template correctly (or at all).
Switching to a core theme (garland) appeared to fix the problem. I tried re-installing a fresh copy of Marinelli and was still broken. I haven't tried another contributed theme.
Any suggestions? I've already cross posted on the marinelli project and am awaiting a response.
Thank you very much for any assistance. The site can be viewed here: http://www.porterworkstest.seanporterdp.com
