Thanks for responding, Steven. I tried the Markup Validation Service, and it reported no less than 47 errors, for example: "Bad value images/Tory Burch.jpg for attribute src on element img: Whitespace in path component. Use %20 in place of spaces."
About 30 of those, and: "Line 14, Column 47: Element meta is missing required attribute name. <meta property="og:description" content="" />"
As far as I can see, if I replace white spaces in all the titles, that's what the pages would diplay, like "Tory%Burch."

Any help with this will be very much appreciated. The site works fine with Windows 8 and Windows 7, but Mac users tell me that only half the images and thumbnails load, and even the splash page is scrambled.
