After running my webpage for about 6 months now I neede to create more webpages for different branches of my "business". So I upgraded my page to a multi site. I know I wasn't supposed to do this since my page is older than 1 month but I thought I'd take the chance.
My installation is in a sub-directory and wordpress by default told me to use subdomains. (This surprised me a bit since i thought that when running a multi site from a sub-directory I had to use sub-directories?)
Everything seems to work fine, except that when I try click into my posts I get the "404 - page not found" error. How can I fix this?
Help will be really much appreciated!
