For some reason, the primary navigation is floating left only on the WooCommerece cart and checkout pages. This is the first time I’ve used the ‘navigation as header” option.
Thank you for pointing me in the right direction, David.
The offending code turned out to be:
.woocommerce img, .woocommerce-page img {height: auto !important; max-width: 30% !important; margin-left: 30px;}
I used to manage the support department for Macmillian Computer Publishing and supervised the Arthur Andersen Tax Technology Group support. You guys are much better than we ever were. Greatly appreciated!
