Description of my issue:
ERROR. jQuery and/or jQuery UI have not been loaded. This usually means that you have to change the permissions of media/com_akeeba and all of its contents to a least 0644.
I have the identical issue described in 16908
I have done everything he has done...
I have also done this
Delete the directory media/akeeba_strapper and the directory libraries/fof from your site.
Extract the installation ZIP file of Akeeba Backup on your computer.
Upload the akeeba_strapper directory which was extracted inside your site's media directory.
Upload the fof directory which was extracted inside your site's libraries directory.
If the problem persists you have a third party plugin which screws up the Javascript on the page.
and it does persist.... how do I figure out what could be the problem plugin?
