Wordpress Super Cache Ubuntu 12.10

Posted November 5, 2013 2.3k views
I successfully installed the canned wordpress/Ubuntu 12.10 and did a few minor tweaks according to so far, so good... the blog part of the site seems to have trouble with WP Super Cache and shows blank pages, or shows pages after multiple refresh cycles only, even in the admin panel... I wonder what the issue is and if there is a fix? I do have a hunch that it has to do with permissions.

Check the owner:group attributes. What's the output of
ls -la /path/to/WordPress/installation/

If you see root:root sprinkled in there, execute
sudo chown -R www-data:www-data /path/to/WordPress/installation/
owner for everything is wordpress
Did you add Apache to the WordPress group (Apache traditionally runs as www-data)? Otherwise, check out How To Install Wordpress on Ubuntu 12.04; although, you'll get A LOT better performance with Nginx (especially if you're using a caching plugin) over Apache. See The Importance of Caching WordPress. Then, check out How To Install Wordpress, Nginx, PHP, and Varnish on Ubuntu 12.04.
