PHP 5.3
Apache2
Ubuntu Server 12.04
Upon "Save Configuration" button click, under admin/config/development/performance, a "HTTP Error 500 (Internal Server Error)" is shown and apache error.log reads:
HP Fatal error: Cannot create references to/from string offsets nor overloaded objects in /media/sf_drupal8/core/lib/Drupal/Component/Utility/NestedArray.php on line 158, referer: http://drupal8:8890/admin/config/development/performance

It's likely this issue predates Contrib.social: some issue and comment data are missing.
The IS mentions php5 which is no longer supported.
So is this still a needed task for D10+?
