Error: Floatbox does not support quirks mode.
This error message can only occur for customers using the LaunchRock widget.
If you do not have the doc type defined correctly in the html markup on your page, it could cause this error.
To fix the error, you need to define a doctype in the first line of your index.html file. Copy and paste this code above your opening < html > tag:
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
Here’s a brief tutorial to check out for more detailed explanation of doc types:
