Static pages shows 404 error

This plugin makes the categories and static pages show an error page, a blank page.

I found a solution for categories, just delete this line in advanced-permalinks.php

$this->add_filter (‘category_rewrite_rules’);

If you delete this line, the categories work fine.

Now the problem are the static pages, still showing a blank error page. I didn’t find any solution in the entire Internet. I think this might be difficult since entries and static pages share the %postname% ID.

?Any solution? Thanks.
