From the sounds of things, it looks like your I.P. address has been blocked. It is most probable that your I.P. address was used by a vandal/ToU violator what caused wikia to globally ban their account and their I.P. address (especially since, as SuperSajuuk said, that you can't tell from your contributions).

I suggest contacting Wikia through Special:Contact/General and explaining what happened to them. Best of luck.
