Description of my issue:
I am unable to upgrade Akeeba Backup from version 4.73 to 5.30 on my Joomla version 2.5.28 site.
Using the Joomla Extension Install Manager, I get the error messages shown in the attached file.
I have tried to install pkg_akeeba-5.3.0-pro.zip and also com_akeeba-pro.zip (located inside the package file) without success.
Please help. Thanks.
