I use both the Mac and a PC and I published directly from Adobe muse to my website and manage through business catalyst however this time Adobe muse is telling me that it cannot find my web sight so I went to business catalyst and I try to publish from there by adding my domain manually but business catalyst give an error message that The domain is already in use. How is that? Could be that the publishing history is saved in another duplicate file muse file always published using the publish menu in Adobe muse for the same website with no issues
The domain may have been applied previously at some time or it could be some odd glitch.
I would recommend reaching out to direct support via case/chat and provide them your site URL and the domain that you are attempting to add so this can be looked into further.
