Okay no errors in logs but this maybe because you have run Empty Logs after running Delete Reports so the log info is lost, and it seems there are reports existing because the only report sent was EditSongs0001
I wonder if the issue is simply that Delete Reports did work, but then you were looking at an old cached page on your PC and this had links to files that no longer exist, hence 500 error.
Or is it maybe that you have SongKong installed on Melco AND SongKong installed on PC. Then you have used web-browser on PC to connect to SongKong on Melco and then delete reports on Melco, but then have also run SongKong directly on PC so you see reports remaining on PC because you haven’t run Delete Reports on the PC version ?
I deleted all logs manually on the melco by accessing the logs and reports folders and just deleted them in windows explorer as it didn’t work using a web browser?
I then made a change to one album just to see if the reports were being created successfully and they are as I know only have one report showing?
This is the only way I edit the metadata, through the web browser as I don’t use the actual pc version of Songkong.
It’s no biggie as I can manually delete the files, I suppose as all my Melco is backed up I can if I really feel the need to, just reformat the drive and do a fresh install.
