Fix for WordPress 3.1 broken permalinks
After the update to WordPress 3.1 many complain about the permalinks not working anymore. Pages and category links are broken.
There is a quick fix that solves the problem and make all pages, post and categories work again.
The problem is into one of the plugins that are installed.
Until now, 2 plugins have been reported as containing bad code. “Simple Tags” and “Multipage Toolkit“.
In order to fix your WordPress, edit the plugins mentioned above and replace the line:
$wp_rewrite->flush_rules();
with
/* $wp_rewrite->flush_rules(); */
After that, rebuild your permalinks structure: go to Permalinks page and press “Save Changes“. Some recommend to do it twice.
Whenever you install another plugin search for flush_rules() into its code. It is not recommended to use it. Any other plugin containing this line of code $wp_rewrite->flush_rules(); has big chaces to break the permalink structure.
