I had a user recently who reported an issue with my plugin's options page not loading. They would click on the "settings" link but only got a blank page.
There was also an issue with the rich text editor showing up on the category edit screen.
I could not figure out why, on almost every other site but their's, the plugins loaded fine. We disabled all plugins except mine and still could not get the plugins to load properly.
Some time passed and I got an email from the user that he had resolved the issue (WP 3.1 site) by editing the file wp-admin/includes/misc.php
$got_rewrite = apache_mod_loaded('mod_rewrite', true);
$got_rewrite = true;
Anyone have any insights into why the unedited file might cause issues with plugins?
