Hi there,
Those copies are downloaded and installed from ConvertPlug directly and I think, it’s not related to the plugin’s current coding or bugs. The fact that we can install that addon means on our end means it works.
And Darshana simply added the addon he installed on his setup directly from ConvertPlug. What’s needed to be solved is the reason why it won’t install. Even if you get the latest version of the plugin, it may still won’t install because the installation is done between your site and ConvertPlug update/install server.
