I was testing WP-Fastest Cache on my main blog and, after changing back to WP-SuperCache, I noticed I was not able to retrieve the articles published on the blog. WLW was trying and trying and kept on trying and no deal. Others blog worked just fine.

After two days of digging, I found the problem. This line in wp-config.php

define(‘WP_MEMORY_LIMIT’, ‘1024M’);
