Internal Server Error! Please Help!

Ok, so I had just put in my permissions file and it was working fine but then the next day I try and go on and it just says "Disconnected: Internal Server Error". I searched through the console and I tried to fix everything that had a "SEVERE" before it but nothing works. I really need help! Thanks!

P.S. I own a fairly sized server, so I have a lot of plugins. Here is the important part of the console log. Thank you so much to whoever fixes this issue I am having. I have been trying for HOURS to fix this with no luck.
