Forgive the avalanche. Where does one find videos in the FTPFTP FTP is an acronym for File Transfer Protocol which is a way of moving computer files from one computer to another via the Internet. You can use software, known as a FTP client, to upload files to a server for a WordPress website. https://codex.wordpress.org/FTP_Clients.? An existing video cuts out audio-wise (it’s already been published) 3 minutes in. I’ve set it back to “Pending Review”. Looking at a Twitter conversation it appears that the producer has already put the “fix on the FTP”. So, how does one go about finding this video, and therefore the correct short code to replace the broken video? (It’s not in the Media Library.)
