Moving a customers WordPress site to a new hosting plan I ran into this error.
This turned out to be an semi-easy fix. The website size was too large for the hosting. Well not really; however, Akeeba requires 2.5 times the size of the site to fully extract the site.
I looked at the website files to see where I could trim some fat. The site was 400 megs. There was a folder called “wp-snapshots” which held a backup. I removed all the extraneous files including my first Akeeba backup. Made a new backup which was only 40 megs. This time when I ran Kickstart the site installed without an issue.
I hope this helps someone else out there…
