If you encounter an blank screen while trying to embed your modules in LibGuides or a different webpage, be sure to check your page source for errors. If any of the errors are an "X-Frame-Option" error, then the website where you're trying to embed the modules is not allowing any embeds. You can read Mozilla's information about X-Frame-Options for more detailed notes.
There are different permission levels for embeds with X-Frame Options:
- X-Frame-Options:DENY - This does not allow any embedded content on the website at all. Items must be hyperlinked.
- X-Frame-Options:SAMEORIGIN - This means that the website only allows embedded content from the same website domain.
- X-Frame-Options:ALLOW-FROM http://frame.credocourseware.com/
