Issue Bopen_basedir
How to fix PHP Open Base Dir or “open_basedir restriction in effect”?

Solution 1The php.ini setting open_basedir limits file access for PHP scripts to designated directories.A limited number of hosting providers feel that without this setting your site is less secure, while this can easily be disputed it’s still a fact that some hosts will not disable it.Below are two options that you can work with your hosting provider on to get around this security setup configuration:

  1. Disable: Work with your host to see if they can disable or temporarily disable this option on your account, to see if itsconflicting with Duplicator.
  2. Configure: Work with your host to add all the ‘concerned folder path’ where open_basedir is restricting access this should include all filesand the root folder where your WordPress install is located; for example:
    open_basedir = /public_html/mysite/

The package process may still work if this check fails, however because this setting tends to introduce other possible side effects it’s desired to have it disabled.
