Warning: Invalid argument supplied for foreach() in /public_html/wp-content/plugins/civicrm/civicrm/install/index.php on line 769

I'm also receiving the following under PHP Configuration: MySQL support not included in PHP.

I'm using Wordpress Version 4.6.1, CiviCRM Version 4.7.12, and PHP Version 5.5

I'm not sure if they're related issues or not.

Any advice?

Thank you

  • Could you please update your question to include your WordPress version, the version of CiviCRM you're trying to install, and your PHP version? Thanks! Oct 18, 2016 at 16:38

It sounds like you might be getting affected by this switch to require the mysqli extension: https://civicrm.org/blog/totten/psa-please-verify-php-extension-mysqli
