 * I have added a custom HTML Widget that has not been displaying. When I look at
   the debug messages, I have the following error:
 * A preload for ‘[https://a0.muscache.com/airbnb/static/packages/dls/dls-lite_cereal-d9f6fdb2a0dd4a18c37f8ee01de8ec3d.css&#8217](https://a0.muscache.com/airbnb/static/packages/dls/dls-lite_cereal-d9f6fdb2a0dd4a18c37f8ee01de8ec3d.css&#8217);
   is found, but is not used because the request credentials mode does not match.
   Consider taking a look at crossorigin attribute.
 * I’m new to using WordPress and need help resolving this issue. Thanks in advance!

 * Hello Heather,
 * Are you trying to embed a listing from Airbnb? There’s also 405 error, which 
   indicates that Airbnb’s servers rejected the request to load something from their
   site. Is the Airbnb listing you’re trying to embed still available? If it is,
   you could try copying the embed code again and pasting it into the widget.
 * I tried to embed a listing from Airbnb using a custom HTML Widget and it works
   okay on my site.
 * So if the listing is still available but doesn’t work on your site, could you
   please try the following, as this may be a plugin or theme conflict.
    - Please attempt to disable all plugins, and use one of the default (Twenty*)
      themes
    - If the problem goes away, enable them one by one to identify the source of
      your troubles.
