How can i convert my videos to HTML5 format (MP4, Ogg, WebM) without installing FFMPEG ?
You can convert videos without installing in your server FFMPEG, try https://convertio.co/video-converter/ to convert videos online or use VLC Player software (here how to convert using VLC Player)
Dashboard doesn't display and i get this message "Failed Cache Storage is Not Supported on this Platform"
Make sure cache folder exist in Root/administrator/ folder of Joomla, if doesn't exist please create it.
