I don't know exactly what is the reason. Until 17th of Feburary WordPress backup to Dropbox plug-in working. Today, when try to manually backup WPB2D plug-in never started backing up. I have uninstall and deleted plug-in, then I have deleted /wp-content/backups/ folder, nothing sucess.
Above mention folder alwasy shows "index.php" file and that file contain "<?php
// Silence is golden." message.
Then I have deactivated W3Total cache and run the backup task, then it started backup. But it shows "Approximately unknown% complete. View uploaded files»".
Actuatually what is the reason, I think it's this plugin latest update issue. Am i correct or is it my side issue?
