  • I just installed this extension and there is not any conflict just showing below one with red color in rewrite explanation "Red class name means that probably there is conflict, initial class has been overwritten by this class, but this class is not used. You should check if this class doesn't contain any important methods or changes, which should be used." – Jamil Ashraf Apr 27 '16 at 16:16
