 * Hi there,
 * Am running the latest version of WordPress, using a Headway 3.4 child theme.
 * When I activate WP Flogin I get this error message:
    Fatal error: [] operator
   not supported for strings in /home/mywebhostusername/public_html/mywpwebsite/
   wp-content/plugins/wp-flogin/wp-flogin.php on line 97
 * Any recommendations aside from checking for plugin conflicts?

 * The line uses the short array syntax, which replaces array() with [], and that
   is valid only on PHP 5.4 and greater.
    This is probably the origin of this issue:
   are you using a PHP version < 5.4?
