I'm having issues with a SiteBuilder Account that uses a reference checkout. I've generated a SSL .csr/.crt/key successfully, but when I change the domain settings to be secure, the site automatically goes into maintenance mode. When I change it back the site pops up for a few seconds as https and then reverts to http again. Anyone experience this before? Note this is for sitebuilder and not suitecommernce advanced ( sites a little old school).
