Error message

I keep getting the following error messages in a fresh install of 3.9. I love the look of the product. I have tried the wp plugin and the downloadable free version – saving as a wp plugin. I am interested in the commercial unlimited version, if this error can be resolved.

It does work well on the desktop, but in WP 3.9 it does not. These are messages I receive when I have the debug turned on.

Hopes there’s a cure. Thanks.
