We have a n older site that was created in MOSS 2007 with an internal URL (default zone having windows auth) and then was extended to use FBA with an external URL. The site was converted to 2013 a few months ago.
Users use the external URL to access the site. It was found that when they signed up for an alert the URL in the alert was using the internal URL which of course they could not access.
The external URL was then set as the default zone and the internal URL was set as the internet zone so that the proper URL would be used in the links for the alerts.
However the content source for this site is set using the internal URL. Around the same time the site search stopped working. We're thinking this could be the cause.
If it is, this site can't be the only one set up this way. Is there a way to have the alerts working with the correct external URL and having the search working as well?
