I am glad to hear that Crio is working for you so far!
The
first issue is something our development team is currently working on
and hopefully we will be able to get it patched soon. In the meantime,
you manually set the Page Template for your homepage to use the No
Sidebar setting instead of the Global setting and that should get your
content to display as expected.
When setting the Background Image for the header you should be provided with the option to Skip Cropping after clicking the Select and Crop button.
I hope that this helps you make the appropriate customizations on your website and please let us know if there is anything else that we can do to assist you, we are always happy to help!
