I am having a similar problem, I recently tried moving my wordpress to my sites root and I changed the home and blog url to my root then moved everything the home page worked but that was it all the rest of the pages didnt, I know its a permalink problem but i cant even login to change it everytime i go to http://www.sypherav.com/wp-admin/ it says
The requested URL /login was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
I checked on myphpadmin to see if the blog url was right and it was, I also tried deleting my .htaccess file, that did nothing, i tried changing the permissions of my .htaccess file, that did nothing. so then i had this idea why not move the wordpress back to where it originally was, so i went into myphpadmin changed the blog url back to http://www.sypherav.com/client (the original wordpress location) again the home page worked just fine, but then when i tried to navigate to other pages or to login i get the same error! can somebody please help me!!! i dont know what to do im guessing it has something to do with the .htaccess file but i wouldnt even know what code to change in there this is how my .htaccess file looks
IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti*
<Limit GET POST>
deny from all
allow from all
<Limit PUT DELETE>
deny from all
i feel like ive tried everything...
