Hey there,
I followed the instructions to change my blog name from http://www.site.com/wordpress to http://www.site.com by changing the URL directly in the directory using phpMyAdmin (http://codex.wordpress.org/Changing_The_Site_URL#Changing_the_URL_directly_in_the_database).
I changed the “site_url” and the “home” value, just as the instructions and as Moshu instructed. However, the instructions then tell you to delete the wp-content/cache folder, which was nowhere to be found in any of my directories. When I checked out my site, it was no longer loading properly. I went back into the wp_options table and changed the URL back to http://www.site.com/wordpress and site loads correctly again. Any ideas as to what I am doing wrong?
Thanks in advance for any assistance!
