LinkedIn (invalid redirect_uri. This value must match a URL registered with the API Key.).
This sounds like the application is not set up correctly for the OAuth 2 "Authorized Redirect URLs" setting. An example of the proper format for one of the URLs is:
https://www.frontmatter.com/index.php?option=com_jfbconnect&task=authenticate.callback&provider=linkedin
.
If you have https enabled on your site, or other ways to access your domain (like www and non-www), add them all in your LinkedIn Application as separate entries.
Twitter (bad request token)
The two most common causes of this issue are:
1. Your Twitter Application wasn't set up properly
2. You didn't copy the API Key and Secret properly to JFBConnect
Please verify that you application is set up properly with our
Twitter Application setup guide
. If you're still having a problem after this, please let us know more details (like privately messaging us screenshots of how your twitter app is set up), etc.
