The problem is actually from the static page Extension.
To resolve this simple go to this file
\extensions\igniter\pages\database\migrations\2018_06_28_000300_create_pages_table.php
then replace line 50-91 with below
[
'language_id' => $language->language_id,
'name' => 'About Us',
'title' => 'About Us',
'heading' => 'About Us',
'permalink_slug' => 'about-us',
'content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
'meta_description' => '',
'meta_keywords' => '',
'navigation' => 'a:2:{i:0;s:8:\'side_bar\';i:1;s:6:\'footer\';}',
'date_added' => '2014-04-19 16:57:21',
'date_updated' => '2015-05-07 12:39:52',
'status' => 1,
],
[
'language_id' => $language->language_id,
'name' => 'Policy',
'title' => 'Policy',
'heading' => 'Policy',
'permalink_slug' => 'policy',
'content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
'meta_description' => '',
'meta_keywords' => '',
'navigation' => 'a:2:{i:0;s:8:\'side_bar\';i:1;s:6:\'footer\';}',
'date_added' => '2014-04-19 17:21:23',
'date_updated' => '2015-05-16 09:18:39',
'status' => 1,
],
[
'language_id' => $language->language_id,
'name' => 'Terms and Conditions',
'title' => 'Terms and Conditions',
'heading' => 'Terms and Conditions',
'permalink_slug' => 'terms-and-conditions',
'content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
'meta_description' => '',
'meta_keywords' => '',
'navigation' => 'a:2:{i:0;s:8:\'side_bar\';i:1;s:6:\'footer\';}',
'date_added' => '2014-04-19 17:21:23',
'date_updated' => '2015-05-16 09:18:39',
'status' => 1,
],
Note that this works for me
