What should i do about this fight with my best friend?

okay so my best friend victoria and i have never got in a fight before until 2 days ago. so a while ago victoria rated my other friend adriana a 7 on facebook. adriana didn't like that. then a few days ago victoria liked adriana's like/dislike/rate status. and adriana wrote: like: you're amanda's friend (i'm amanda) dislike: you rated me a 7. rate: 6. so then they started fighting and cursing each other out. i told them both to knock it off because its so stupid. victoria got mad at me for not sticking up for her. but she knows adriana is my friend too. we haven't talked in 2 days because of this stupid facebook crap. i think she's being ridiculous because this is a really freaking stupid fight to get into. i'm not apologizing because i don't think i did anything wrong. but i miss her. so what should i do?
