Don’t ye be alarmed! Thar’s nuttin’ wrong wit’ the site. Tis’ a plug-in for International Talk Like A Pirate Day what makes all the CSS go haywire. All will be restored on the 20th.
This drove me absolutely nuts last year, tearing apart code, analyzing and such only to find it is this blasted WordPress plug-in to blame.
In the meantime, have fun talking like a pirate today!
