After moving my WP 3.1 site to a fresh 3.1 install on another server and uploading a copy of WP-Contents, everything still worked fine. It also worked after switching to the uploaded theme.
After importing the old database all I get now is a blank page. If I restore the database and import all but the wp-options table the site works again.
What area of the wp-options table do I start looking at as the problem?
