I started a db using one of the templates that did not use the classic theme. I converted all of the layouts to 'classic' prior to trying IWP. Followed the instructions, the dp appears on the web page, I'm allowed to sign in with my credentials, but then get an error that the 'classic' theme wasn't used.
Do I have to start from scratch with the classic theme in order for IWP to work? Is there a way around this error?
