Maybe files are encoded by our site when they encoded the license number on the program who knows. I can tell you though the distribution files are not all dated 2-20 for sure
Thanks for the typo on Maximum side option
As far as PHP file max upload lets explain what that is. That is the maximum file upload size allowed in PHP defined by PHP. This option allows you to explicitly set this to match the filesize in your PHP settings so users get a warning saying they are trying to upload a filesize that the server will not allow. If you did not have this then it would default to PHP which alot of times just does a white page with no error message. It has nothing with allowing PHP files to be uploaded.
