.  It doesn't look like site for this plugin exist anymore, but good new is that I think I have contact to developer of that plugin and we can investigate with him the issue that plugin is causing. I send him a message so I can get a copy of the plugin and test in my environment and see what is reason for that conflict. It might be that this plugin is no longer compatible with new WordPress - but I will know soon more and let you know.
