My Web Widget (Classic) is not showing on any page other than my Help Center. This only happens if I have the Help Center and Contextual Help options selected in the Web Widget (Classic) settings:
The Web Widget (Classic) only renders content based on what it has access to. If the widget is not showing up on a particular website, most likely you have the option Require sign in enabled in Guide. For more information, see the article: Restricting Help Center access to signed-in end-users.
Having this option enabled, with Help Center and Contextual Help features selected, prevents the widget from loading for unauthenticated users. If you enable other options, like Contact form, the Web Widget (Classic) will work again.
If this does not solve your issue, visit this troubleshooting guide: Troubleshooting Guide: Why is the widget not showing on my website?
