Your calendars and event alerts only load on websites you've added to Revisual. On any other website, the browser refuses the embed. So add your website before you embed a widget on it.
You don't need to add a website to share a calendar's own link or QR code.
Add your website
Step 1: In the left-hand menu, click Websites, then Add website.
Step 2: Under Domain, type your website's domain, for example mydomain.com. You can also paste a full address from your browser: Revisual removes https://, www and the rest of the address for you.
Step 3: Click Add website. It appears under Allowed domains.
Subdomains and test addresses
Each subdomain is a separate website. If your calendar is on shop.mydomain.com or events.mydomain.com, add that address as well as mydomain.com.
The same goes for test and preview addresses, for example a free wixsite.com or squarespace.com address. Add each one you embed on.
How many websites you can add
It depends on your plan. The bottom of the Websites page shows how many you've used, for example 0 of 5 domains used. To add more, click Upgrade plan.
Using WordPress?
When you connect your site with the Revisual plugin, your website is added for you. See How to add Google Calendar or Outlook events to WordPress.
Calendar not showing on your website?
Check that the exact domain is under Allowed domains, including any subdomain.
Check that your calendar is published. See How to publish your calendar and add it to your website.
