  Looking into file htdocs/lib/db/install.xml (line726) – table view_layout

  A Quick analysis of the problem indicated the following
  The column rows in the table view_layout is causing a problem (as of MariaDB 10.2.4 rows is now a reserved keyword (https://mariadb.com/kb/en/mariadb/reserved-words/)

          <TABLE NAME="view_layout">
              <FIELDS>
                  <FIELD NAME="id" TYPE="int" LENGTH="10" NOTNULL="true" SEQUENCE="true"/>
                  <FIELD NAME="rows" TYPE="int" LENGTH="10" NOTNULL="true" DEFAULT="1"/>
                  <FIELD NAME="iscustom" TYPE="int" LENGTH="1" NOTNULL="true" DEFAULT="0"/>
                  <FIELD NAME="layoutmenuorder" TYPE="int" LENGTH="10" NOTNULL="true" DEFAULT="0"/>
              </FIELDS>
              <KEYS>
                  <KEY NAME="primary" TYPE="primary" FIELDS="id"/>
              </KEYS>
          </TABLE>

  To hotfix the issue I´ve updated the column rows to numrows in the
  following files after which the installation continues as expected and
  Mahara functioned properly.

  htdocs/lib/db/install.xml (line726) rename ´rows´ column to ´numrows´
  htdocs/lib/db/upgrade.php (line2407) rename ´rows´ column to ´numrows´
  htdocs/lib/db/upgrade.php (line2441) rename ´rows´ column to ´numrows´
  htdocs/lib/upgrade.php (line1233) rename ´rows´ column to ´numrows´
  htdocs/lib/upgrade.php (line1292) rename ´rows´ column to ´numrows´
  htdocs/lib/view.php (line1185) rename ´rows´ column to numrows´ 
  htdocs/lib/view.php (line2935) rename ´rows´ column to ´numrows´
