So I went through a lot of pains to finally get Multisite to NOT create subsites with messed up URLs, but I still have duplicate tables or whatever you call them in the PHPMyAdmin area.
A few pieces of info:
- When I upgraded to the stable release of 3.0 I was told a duplicate network was detected.
- I battled poorly formed URLs of my subsites due to DreamHost code in the wp-config file.
- I have no idea if these duplicate entries really effect anything, or how to effectively remove them without messing anything up.
