For the past few days I've been having an extremely hard time trying to edit things and what not on wikia. I think I found a few things that can help fix this if anyone else comes across this:
1.) Try to delete all of your browsing history, cookies, downlaods, etc.
2.) Re-install your browser (I use chrome)
3.) You can change your preferences on wikia by going over your name and selecting "My Preferences". Then change your style from "Wikia" to "Monobook" (I like wikia MUCH better.)
Yay, I can finally edit things again :D
