Regarding the 404 errors, it looks like it’s catching the end parenthesis in both URLs; if you take that out, both pages are accessible.
All plugins are up to date.
I did change the folder name, in order to avoid any potentially unwanted future updates, as the theme has been customized. But I did not edit the Feature page template.
