i have weird file (in attachment). Every time when I open this file, Song is duplicating in database. Why? I have some songs which do it.
There's a setting for importing songs from the service, and I'm guessing that somehow OpenLP is unable to determine if that song already exists in your database. Go into the settings and de-select that setting, and that should at least get around this problem for now.
Yeah, but then all songs aren't added.
I'm looking at why. That was just a suggestion for getting around the problem right now.
