If you share your website on Facebook, you may notice an older look in the image. While this is updated from time to time, you can do this yourself too:
- Save your template settings again. You'll have to make a small edit for the Save button to become available, such as changing a color and then changing it back again.
- Go to https://developers.facebook.com/tools/debug/sharing/ and enter your URL (e.g. https://www.mycompany.com).
- Click on Debug, then click on Scrape again.
- Wait a few minutes, then repeat steps 2 and 3 to update your image.
