Same here. I can access it but it ends up blank. Wikia's staff mentioned on Twitter a few hours ago regarding immediate efforts to fix the site, as it was very problematic then - I couldn't log in, ads weren't loading (though I prefer it that way :P ), special functions that used CSS wasn't functioning properly, and I was unable to log in.

So yeah, it's most likely a universal problem.
