I'm using wordpress backup to dropbox including the .zip extension and everything works fine. On my dropbox i now get every day a nice 32MB backup without any issue.
Now the problem: I like to test the restore. So i uploaded the folder "restore" on another webspace. I call mywebsite/restore/ and it starts. It's asking for permission to connect to my dropbox without problems. Now i choose the file that i want to restore. And here is the problem. I get a message that says: "Unable to open file handle for /var/www/vhosts/XXXXXXXXXXXXX.com/httpdocs/mcp/XXXXXXXXX-backup-2013-04-06.zip"
Note: message details replaced here with XXXXXXXXXX
What to do?
