Description of my issue:
I am trying to backup to dropbox:
I select this option from Configuration > "Post processing engine" press configure and then when I press the first "Authentication Step 1" button, the pop up window is blank ????? (please see screengrab)
I successfully set this up OK 2 days ago with no problem. on a differnt account on the same hosting server.
I have tried:
• restart
• other browser
• other machine
• download new akeeba zip and re upload
• same proccess with another account - I had the same issue.
Hope you can help
Thanks Brett
