[mntent]: line 12 in /etc/fstab is bad when configuring Backup

Hello!

I have a PunBB Jumpbox v1.1.9 and I am running into an issue when trying to configure automatic backups through Samba/Windows File Sharing.

When I input all the settings and click on Configure Backups, I get this error message: [mntent]: line 12 in /etc/fstab

Any ideas? I have another PunBB Jumpbox using the same settings and it works just fine :(

Thank you!
