This will be in your email 🙂 .

Thank you.
Correct. I have actually created a ticket now for you so you can just reply to that ticket once your community is in a broken state tomorrow at 8am ET with the upgrade and our team will take care of it from there. Look forward to assisting you.

These are generally only reset when you set your main URL. You should use the same URL for testing until such point as you wish to change the main URL. Many people will use a subdomain for this that they can point elsewhere if required.
I can see there is nothing on the test URL at present, so have reset it on this occasion for you.
 
And yet here you are, speaking with support 😉 We haven't removed support. We simply do it here on the community and not via ticket. I have taken a look at yours, and you would not be able to change your test URL in any case, as you still have an installation at your current test location.

How would I go about changing my test URL?

Yes, you will need to Uninstall that corrupted copy so that there are no "left-overs" from it that may interfere with its reinstall.
Once that has been done, follow the steps in our guide to add the product:
Download a fresh copy of the software, upload all its files, then perform the minor update that will be required (it's a patch and will not affect existing items) by visiting the upgrade URL directly (your-site.com/admin/upgrade/) and perform the minor update.
Once that is done, login to the ACP, go to the Applications page, and you will see Pages ready to install, on the bottom of the page. Click its icon to install it, and it should complete without error.
