Some Problems With New Server

[Jordon_Crider]

I'm having some issues with a new private server I set up. I've been trying to get God Mode to work, as I recently moved to Tekkit Lite from Classic, and I miss the rings' ability to fly, but nothing works. I've gone into the server.properties file and set flying to true, and I've made sure that ops can enable God Mode, but when ever I input the "/God [My Name]", it says that it is an invalid command. Note that I have tried every combination of caps in my name, tried "/god" with the lower case, and nothing works. I can't find anything else to edit or change, so if someone could possibly tell me what I'm doing wrong or not doing, I'd really appreciate it.
