Fix Invalid Parameter, LinkedIn Submitted URL cannot be empty, Tweets with no link
This issue is usually caused when there is a problem with the link for your post. Either Revive Old Posts cannot create the link(which in some cases are needed by the social network) or there is an issue with the shortener you have chosen.
Try setting your shortener to a different provider such as is.gd and test this again to see if the issue still arises. If it does then send us a ticket here.
