QooQee Muse Blog has a server side part, but BC (Business Catalyst) does not support any kind of server side functionality. So please make sure that you are running your blog on your main hosting not on BC.
If you were planning to use BC only to test your blog or website, you need to run the test on your own server/domain in order to realize that if your Blog is fully compatible with your server, before you go further with the design.
