I'm looking at a problem on a WordPress site I didn't build and the company that did are no longer operating.
The site is fairly basic with no user membership this etc etc.
The site holds all its content and configuration in the wp_ tables, so is properly database driven. The site holds development and production data in the same database.
The problem is that when a user on an iOS device clicks on the contact us button instead of displaying the contact page it shows a logon to the old companies development site. If you cancel the logon a couple of times it will go and then you are redirected to the correct contact page.
I've looked through the wp_posts data and can't see anything obvious that I could change.
I'm guessing there is a database entry somewhere that is just being used for iOS devices and is incorrectly configured to show the old development site contact page.
Nobody noticed the error until a user informed them so it's probably been there since the beginning rather than a problem with the server, ios update etc.
Does anyone know where I should look? I'm guessing a probably won't show this error because it is not really an error, more a feature that is activated to enable development work/testing and should not be.
