 * Hi,
 *  Thanks for your useful plugin.
 *  I’m experiencing warnings like this:
 * `Got error 'PHP message: PHP Warning: Undefined variable $fvmf in /var/www/clients/
   client5/web13/web/wp-content/plugins/fast-velocity-minify/inc/common.php on line
   2172'`
 *  This is last version 3.2.9.
 *  At function _fvm\_add\_header\_function_ you start using:
 * _$fvmf.=_
 *  May be this must to be:
 * _$fvmf=_
 * Best regards.

 * 3.3.0 changed one Warning for another one, may be yo missed to include file wpr.
   php to svn?
