Why we automatically changed your shortener from rviv.ly to is.gd
Rviv.ly is our own custom shortener service which we provide for free with Revive Old Posts. Recently the rviv.ly domain has been added to a blacklist used by networks such as LinkedIn and Twitter to prevent abusive/spam/malicious posts on their networks.
We are in the process of getting our rviv.ly removed from this list as well as adding some more spam checking measures directly into our rviv.ly shortener to prevent any future abuse by malicious users.
In the meantime, we've removed the shortener from the plugin and changed it to is.gd so users' shares are not affected.
