Good Afternoon,
I have an ArcGIS.com map set up and I have the attributes configured for a Parcel Layer Popup window whereby I embed a hyperlink in the popup window then use an attribute value from the parcel layer to finish the url so users are jumped to a Parcel Detail page.
However, when I share/publish my map as an application (Public Information template) the popup window gets screwed up
Try for yourself: Weblink
I have tried configuring the popup/map using Chrome (Version 40.0.2214.115 m) and Firefox 32.0.1
