I recently upgraded to PRO Version and the reason i upgraded is for file versioning as my files were not updating in free version after modifications in css or other files. So i uninstalled the free version and installed the proversion of CDN for Joomla, i made changes to some CSS files and still those changes are not reflecting in my website. I cleared the cache as well but no result. Please help.
In versioning file type option i have css,js & File Versioning is enable. Time stamp is being added to css file on CDN but code is not updating.
CDN for Joomla! Only controls the url of the files used in your website. It does not control if and how your CDN provider caches your files.
Again, something you would have to ask Cloudfront support about.
