If you face the problem that your backup, restore or migration stuck or does not start at all, it can be caused by the work of another plugin. In most cases security, cache plugin or any other backup plugin. If use any cache plugin, exclude the file ‘wp-cron.php’ from your cache plugin list.
In order to find out if there is any plugin that conflicts with Backup & Restore Dropbox plugin, just deactivate all your plugins and make a backup/restore. If the backup/restore were finished successfully, you have to find out what exact plugin caused the problem before.
Activate your plugins by turn until you find which one blocks your backups and restores.
When you find it, contact our support team via support(@]wpadm.com and inform about it to let us find the cause of the conflict.
