Drupal search module has suddenly stopped working, how do I fix this problem?

Question

Drupal 6.15 search has stopped working. how can I fix it? I've run the cron and re-indexed, but it still does nothing when searching. Any ideas? I can see the tables that the items have been indexed, but search results show a blank white page.

Answer 1

If by "blank page" you mean completely white, then that usually means there's an error that's being hidden from view. Put this at the very beginning of your index.php (to enable error reporting):

<?php

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

And then try the search. Chances are you'll see the error message, and that will tell you what's going on.

If all else fails, flush all caches and run update.php just to be safe.
