though no changes have been made to the account, the files on the server, nor the domain settings at the registrar, an addon domain has recently begun to simply forward to the primary domain, rather than show the contents of its directory.

addon: minimartcitypark.com
primary: suttonberesculler.com

everything is still located in the same directory as it was before (http://suttonberesculler.com/minimartcitypark.com/) and the settings show no redirect–it looks the same it did when i first set it up:http://grab.by/iXZw

we need the addon domain back in order ASAP. please advise.
