ok. No errors in that file. Size: 9093184. Ends with:
adding: .DS_Store (deflated 85%)
Debugfile size is constant and backup seems finished. While aapanel is still saying "Backing Up, please wait ..."
What other troubleshooting ways are there?
edit oh I just found all my fully finished site backups in /www/backup/site/
none of them of that specific site show under Package Backup in my aapanel. Deleted them in cli, running a backup again, without errors, completed zip in the same directory and aapanel is still showing the notice. Refreshing the screen, and according to aapanel the backup for the site "Not exist". So its a aapanel controlpanel bug?
