I am working on a Random-Quote-Machine project for Front-end-certificate. When I try to run locally my react project and I am able to connect with Twitter, but with codepen.io I get this error:
This has since been closed, and should no longer be an issue. The advice is:
If you are developing this on CodePen, the restrictions prevent the Twitter link from loading in the window. Add the target="_blank" attribute as a workaround.
Or, add target="_top", if that does not work either.
