Update URLs

The site has changed servers, domain names, or whatever, and Wordpress still has a bunch of stuff that links to the old location, even after you've updated the URL's in the Dashboard. What do?

Install this plugin to update all the URL's:

Wordpress corn Jobs

Is Wordpress getting a lot of traffic and touching itself inappropriately? Follow the below to turn off Wordpress's built-in "cron" system, and use a real Linux cron job instead.

1. Disable WP Cron

In your wp-config.php file, add the following line:
define('DISABLE_WP_CRON', true);

2. Setup the linux crontab

- su to the site owner
- crontab -e
- Add:
/15 * * * wget -q -O - http://yourdomain.com/wp-cron.php?doing_wp_cron
