Custom fields not rendering

I have a very weird problem. All custom fields are not rendering on all content types. I create a Basic page which has the default title and body fields and the content renders fine. If I add a custom field to the Basic page content type, the custom field does not render in view mode. I can edit the content type and the custom fields work fine, but as soon as I view it, all of the custom fields do not render. When I do a var dump on $variables in template.php I can see all of the custom fields and values in page['content']. I thought it might be a permissions problem, but it is happening for all users. Does anybody have any ideas to fix this problem?
