So there is a problem with my site, the one in my sig. The main page works fine, but if you want to click on any other link an error message shows. Does it have to do with the hosting or what? So if you all could check it out that would be great! Noc
In the admin panel go to settings -> permalinks and there in the common settings select the Default option. And then save the changes.
You should change permission for .htaccess to 777 (via FTP or cPanel) and then go to settings -> permalinks and update the links type again.
yep, its a permalinks .htaccess issue.. Either turn permalinks off in wordpress =, or fix it via the method sourcer mentioned.
