My goal is to backup the current outdated site to my Joomla site on the Siteground server so that I can update everything and make sure it's working before moving it back to the active site. I've succeeded in installing the version of backup and creating the backup files, but I can't get kickstart to run. I'm using Filezilla, and I've done as suggested for this error by changing the file transfer to binary. This has not resolved the problems I'm having.
The site the backup is from is on PHPwebhosting.com using PHP 7.3.33 and Joomla 3.10.
The site I'm trying to restore it to is Siteground with PHP 8.4.20
Thanks,
John
