There has been an issue in Wikia in the last few days, though it should be fixed soon.

Try to do one of the following things:
 * Try to clear your cache. I'm not sure if it's related, but it sometimes fix some issues.
 * If it doesn't work, try to log in via another browser (might help).
 * If none of those work, you should ask in the technical board in the community central.
