I have a wordpress site that when I change the permalinks in settings it gives me are error 404 page not found when I try to open the page. If I let the permalink to default no problem. When I change permalink to post name, then the error shows. When I try setting month and name no problem.
I downloaded the plugin Google XML sitemap and when I try to open my site url sitemap.xml it shows error loading stylesheet: An unknown error has occurred (805303f4)
