The bot GUI says that the Add-On is not enabled and there isn't a Bot Spawn in the menu? Make sure you have enabled AddOn_SpaceBots for the server, and not the older version of “Talking and Attacking Bots” as AddOn_Bots. Also, some Add-Ons such as Fooly Cooly's Fun Commands and SolarFlare's Decal Downloader can prevent others from loading correctly. Try disabling them if you have them.
