I have a wp multisite installation with multiple blogs that are totally separated websites. I use a plugin for domain mapping.
Right now I am configuring everything and I wanted to remove the /blog slug from the main blog, I did it by editing the settings as "network admin". I used /%POSTNAME%/ and / for category and tags base. The posts opens fine opening www.url.com/postname, but www.url.com/categoryname show 404, I tested changing the category base to anything (like /c) and www.url.com/c/categoryname works.
But I don't want to have a category base I want the category post lists to open on www.url.com/categoryname.
How can this be done?
