WordPress Caching: WP-Cache Plugin – Blank Page Bug Fix

Last week we wrote a quick how-to on caching with WordPress, by using the WP-Cache 2 plugin. It seems that there is a small bug in the code which may effect some people.

After you install and enable the plugin, if you are getting a blank page when you first go to your site, you need to follow these instructions to fix the bug.

1. Disable the WP-Cache plugin.
2. Switch to the “wp-content/plugins/wp-cache” directory.
3. Make a backup of all the files in this directory.
4. Open the “wp-cache-phase2.php” file.
5. Search for “ob_end_clean()“.
6. Replace it with “ob_end_flush()“.

Now, you should be all set. Go ahead and Enable the WP-Cache plugin, and you should be able to pull up your website.
