This is SO typical of Dreamhost, you have a problem and rather than tell you how to fix it they tell you to use something else that does not work so well.
Now I have PHP 5.3 and I tried 5.4 but still Duplicator reports
"The ZipArchive extension for PHP is required for compression. Please contact your hosting provider if you’re on a hosted server. For additional information see our online documentation. "
I moved 13 domains to Dreamhost with this package, but two would not migrate, 500 errors on Restore
I tried Backup Buddy, same issue
Now I want to create a dev version of a site and neither backup or restore will work
I have spent a month messing around with PHP memory and other settings
a dozen support tickets and still I have to waste my sunday trying to get something that works on Hostgator and Hostmonster to work with Dreamhost.
So what do you suggest?
