I installed the plugin, succesfully linked it to my Dropbox account and also purchased the zip premium plugin.
When trying to manually creating a zip-backup, the backup won't finish and always hangs at a certain point:
There's a file created in wp-content/backups but I'm not sure if it's complete.
Also, nothing gets copied to my Dropbox folder and the status of the backup never completes.
I also tried to manually create a standard backup (without zip compression), this also does not complete and gives me multiple of these errors:
There was an error uploading 'xyz' to Dropbox
