When attempting to search the help center for information through the Web Widget (Classic), the widget shows the error: There are no results for ...
The error There are no results for ... occurs when the host mapping settings on your Zendesk account are incomplete.
Complete the host mapping settings on your account. Follow the steps below to ensure they are complete.
A host-mapped address must be added to your Zendesk. Check that this is present within your host mapping settings.
SSL settings and certificate
Ensure that you have hosted SSL enabled as well as an active SSL certificate. Your account must have an active SSL certificate enabled. Zendesk will provide you with an SSL certificate at no extra cost that's included with your Zendesk plan. Alternatively, you can obtain your own from your web hosting provider and upload it to your Zendesk from there.
