After upgrade from 1.6.2 to 1.7.0 the new backup tool doesn’t work. I mean everytime when I choose System Backup, Database and Media Backup or Database backup magento show information:
“The backup’s creation process will take time.
You will need to wait when the action ends.
Do you really want to proceed ?”
but I can’t choose button OK or Cancel. The only thing I can do is refresh page.
Do you have any idea how to fix this issue ?
