When I install Version 4.1.2, the following errors come out:
Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /home/cpgtxos/public_html/forums.glassesadvisor.com/includes/class_core.php on line 414
Warning: Cannot modify header information – headers already sent by (output started at /home/cpgtxos/public_html/forums.glassesadvisor.com/includes/class_core.php:414) in /home/cpgtxos/public_html/forums.glassesadvisor.com/install/includes/class_upgrade_ajax.php on line 731

How to resolve these errors then?
To fix this, edit your config.php file and change ‘force_sql_mode’ to ‘true’:
$config[‘Database’][‘force_sql_mode’] = true;
