I am really sorry for the delay of this reply as it is a weekend for us here.
It seems like I do not have Superadmin privileges to access your backend configuration page, you can refer on my attached screenshot below.
By the way, can you provide us one of the article post URL so we can take a look that link which not working correctly?
Also can you update your FTP access into this section again ? http://stackideas.com/dashboard/site
In case we need to troubleshoot this issue.
