Hi all,
Couple of questions I've got that I'm wondering if anyone here can answer. 
1: With the new version of portals, I'm wondering how to modify the sign-in and registration pages with custom templating etc. as you can't do it locally anymore(?) So I'm wondering if there's a work around which would allow me to make a custom registration / sign-in page using a form.

2: I have modified the profile web form, to change the way the profile screen looks within the portal, however whenever I press update, an error is thrown (as seen below):

We're sorry, but something went wrong. Error ID # [7190471a-4daa-4e95-9638-24a12d06b492]

We've been notified about this issue and we'll take a look at it shortly. Thank you for your patience. 

I can update the same information within Dynamics 365 just fine, but just in the portal it throws an error everytime I try to update, even when no values are getting changed. 

Any help on either point would be greatly appreciated! :)

Thanks in advance
Josh Grant
