Hi Joshua,
I am able to replicate this issue on my local instance. It seems the issue arises when there are steps that are not being shown in the registration process. In your case, the 'About Me', 'Nighbourhood Information' and 'Business Information' are not being displayed in the registration process. When the Previous button is clicked, the page is trying to find those skipped steps/pages in the registration process, which I assume leads to this error.
I will create a ticket internally so the devs can look into this.
In the meantime, you have to either show those pages in the registration process in order for the Previous button to work properly, or you can arrange and move those pages to after the Profile Picture & Canvas step for now(example: http://take.ms/ObVqX).

Raymond,
I choose the order of the steps based on how I thought they should appear when visiting a users profile page. The steps set to "Appear During Registration" are different base on the Registration Profile chosen. For now, if I understand you correctly, I'll need to place any steps set to be displayed during registration prior to those that are not, to avoid the issue when clicking "Previous," correct? This will cause the "About" display to appear slightly different based on the users Registration Profile. For now, this may be a better option then requiring a new user to go through a bunch of steps that slow the registration process, and aren't required. I'll try your suggestion and let you know if I encounter issues.

Thanks,

Hey Joshua,

Until this bug, which I already reported, is fixed, then yes that is correct.
Let us know how it goes, thanks.

I've retested this issue after updating to 2.0.15 and it no longer exists. Thanks for resolving this issue.

Regards,
Joshua
