Sorry for the inefficient posting of the error. Does anyone have any advice for me? :\
I honestly believe it has something to do with an add-on that I attempted to use earlier today. I was attempting to understand user groups and utilized this:


however at the bottom, I was taught that I didn't need the addon at that this would suffice:



Original conversation is located here:


TL;DR: I jumped the gun and installed an add-on that I didn't need and it effectively made the user registration process explode on itself. Solution?
Fortunately this a brand new forum, with only two members (Myself included), so If I need to wipe out and replace a parent folder somewhere, It wouldn't be a loss.

Looks to be an issue with an add-on (is it disabled?) - possibly "brapp" or a conflict with another add-on.

You would need to contact the developer of the "brapp" add-on for support in the first instance.
Interesting. I believe you're right. It seems to be working again after enabling ALL add-ons. Now to determine which one is causing the error and what to do to avoid it. Thank you.

Disable them one at a time until the error reoccurs - that will help you identify it.

The problem is due to an incorrect database setting for the field- the author can resolve it very easily.
