From the look of those errors, you are using version 3.5 of SilverStripe, and PHP version 7 - these two aren’t compatible I’m afraid.

You have two choices:

  1. Update your SilverStripe version to the latest 3.6, which is compatible with PHP7
  2. Use a lower version (5.6) of PHP to run the site.

To follow on from this, SilverStripe 3.6 supports PHP 5.3 to 7.1 and SilverStripe 3.7 supports PHP 7.2.
