When trying to enter Youtube video: Database query G.37.11 error: Data too long for column 'youtube' at row 1
Are you entering only the ID of the video?
If the full link is e.g. https://www.youtube.com/watch?v=dQw4w9WgXcQ&list=RDdQw4w9WgXcQ&start_radio=1&t=0, it's only dQw4w9WgXcQ you want. Strip off the start and anything that might come after the ID.
Thanks AGA (nod)
