Recently I had to move one of my blogs to another hosting account. I moved all files and then did upload a mysql backup. Blog was working but if you click on a post or category you get a 404 error.
I haven't changed anything.
Permalink Settings is /%post_id%/%category%/%postname%.php
Also it has a .htaccess file.
whats the reason for this ? here's the link,
Basically Only the home page is opening. All other internal links are not working returning a 404 error.
