I'm installing WP in a subdirectory (http://domnain.com/welcome)and am getting the error (see below) message in "Appearance>> Themes" & "Plugins>> Installed Plugins" links in the sites dashboard. Its surprising to me I'd only get this error message in those two links. I believe this is something simple I'm doing wrong, and this is the first time installing WP within a subdirectory. I need someone smarter then me to point me in the right direction. What am I doing wrong?
