In admin.cgi, most of the pages load fine (including build all), but there are some pages that take a VEEEEEERY long time to "finish loading," but when they do, there is only a box with "Search Database" in it, or intro writing like "Check which records (128) you wish to validate and then press "Validate ". Only 10 records are displayed at a time. Click on the validate link to open a new window to preview the site." and nothing more.

Why would some pages load fine and others not?

Thanks in advance.
