Category:Help

Sorry for writing here, but I can't seem to either register or make anonymous edits due to a PHP error. Well, category pages work, but not the main namespace, that's why I'm writing here. Any idea how to get around this?

For the reference, here's the error:

[4e2b4d79] /index.php?title=The_H-Town_Wiki&action=submit Exception from line 268 of /usr/share/nginx/html/wikiindex.org/public_html/includes/mail/UserMailer.php: PEAR mail package is not installed
