 * Hi [@vimalfzr](https://wordpress.org/support/users/vimalfzr/),
 * What version of WordPress are you using? The plugin requires at least version
   4.4 of WordPress.
 * If your version is older than that, you will need to update if you want to use
   the plugin.
 * If your version is 4.4 or newer, can you try turning on WP_DEBUG and let me know
   what the error messages say? You’ll find instructions about turning on WP_DEBUG
   here: [https://www.pipeten.com/support/scripting/enabling-wp_debug-in-wordpress/](https://www.pipeten.com/support/scripting/enabling-wp_debug-in-wordpress/)
 * Thanks,
    Angus

 * Hi,
 * We are on WordPress 4.9.8. I’m not sure if [@vimalfzr](https://wordpress.org/support/users/vimalfzr/)
   is having the same issue we are, but upon updating the plugin we also had a 500
   error take down our site. Inspecting the debug.log file indicated that usage 
   of the PHP function ‘boolval’ was the culprit. This function has been available
   since PHP >= 5.5 and our site is still on PHP 5.4.
 * A workaround would be to change the check in the file ‘cf7-material-design.php’
   on line 131:
 *     ```
           if (function_exists('boolval')) {
               $upgraded = boolval( get_option( 'cf7md_options[upgraded_from_v1]' ) );
           } else {
               $upgraded = (bool)( get_option( 'cf7md_options[upgraded_from_v1]' ) );
           }
       ```
   
 * The above is just an example. A check as you see fit would be sufficient. Thanks
   for your time.

 * Hi [@dakao](https://wordpress.org/support/users/dakao/)
 * Thanks for letting me know about this. I’ve released an update along the lines
   of your suggestion.
 * [@vimalfzr](https://wordpress.org/support/users/vimalfzr/) could you try updating
   to the latest version and see if that solves your issue?
 * Thanks,
    Angus
