Hope that's useful.

It's a packaged environment. So would it be causing the problem even though the Shop build is on a different subdomain?

Okay. I'll run it by my hosting provider.

Still getting white screen of death after attempting to save a shipping method...

The error message at the top of the screen is Fatal error: Call to a member function index() on null in /home/pixelsmi/public_html/clients/dev4/perch/addons/apps/perch_shop/modes/shipping.edit.pre.php on line 45

And this is the verdict from my hosting provider...

The AH01797 error is occurring on an entirely different subdomain to the one the Perch install in question is on so I'm not sure why it would be white screening me.

After a certain amount of barking up some wrong trees seems the error occurs when the priority box is left blank while creating a shipping method. Want any more info on this?

Thanks Drew. I've marked it as required in the template.
