Manage Collections Adding New Tracks by Selecting Folder is Timing Out

Hi David,

Importing or adding tracks via the folder selection is timing out for some reason. I have increased the servers php max execution time, post and upload, no change. I exported the music  csv file and have created an upload csv file for the failed collection that works and relinkes the previews/secure, but what I am finding when I export the music csv file again is that the exported csv is collecting the failed uploads and marking them collection '0'.

Q. Do I need to clean the database to get ride of ghost collections?
Q. Any suggestions on server adjusments to correct the upload via folder error?

Thank you for your time. Best regards, Joel
