Nothing will load, funcation error, need help

I believe I have the most current version of WP.

I was editing my function in the Blogo Theme and I was trying to get rid of the posting details at the bottom of posts like date and author. So i saw on the forums that if you put /* or */ that it can remove that part, so T went into function editor and toward the bottom where I saw author I was experimenting and just put a */ and tried to reload to see what changes happen and now nothing on my page will load. Admin won’t load and my site itself won’t load. I can’t access anything. Help?
