Using "Colored Squares" Throws Error

I love the theme, but if you use the colored squares option for selecting a color, every category that contains that product will cause the ajax filtering plugin to throw an error.

Hi olallaskibum,

Could you please update the Ajax Filters plugin as we fixed a few issues with the color squares, so this might have already been fixed?
Simply follow the instructions here. You could also uninstall and then install the Ajax Filters again. Actually we are going to add some new features to the Ajax Filters plugin today, so you can do that later today.

Please let me know if you still have this error after the update.

Best Regards,

So how do I go about getting an update for the Ajax Filters plugin?  I don't see anywhere on the site that allows me to download an update.

Never mind about the "how".  I figured it out after a closer reading of your instructions.
