Template overrides within the default latest HelixUltimate 2.0.18 result in blank registration results page. When I remove the html directory, the page displays better, but when I use the default template Cassiopeia - Default, it displays perfectly.
I have noticed that the informational messages are displayed in a popup on the bottom right corner, but the main content on the website is blank.
Why is this happening and how can I fix it?
