We are happily using many of your extension for many years, including more recently, CDN for Joomla!
Started to notice that some of the resources were not loading from the CDN set, but still from the site itself. Quick investigation showed that for instance SmartSlider Pro plugin order was after the CDN plugin.
Setting the CDN plugin so that it loads after Smart Slider plugin solved that issue.
That made me wonder, by default, CDN plugin order is set to "0" and is one of the earlier plugins to load. Is there any harm in loading the CDN plugin as last in the order? What is your recommendation?
