Hello to everyone,
I am a videographer and I have a site in order to show my portfolio. The site is: videosokratis.gr but without making any changes, the videos in my portfolio have stopped working. It shows a message that the content is not available. The strange is that when I am entering in the administrator panel, into the k2 contents, shows all my videos and also play them. If someone can help me please because its my job in it.....
