I would like to change a bit behaviour of one Smarty function (ie. it is smarty_modifier_escape in cmsms/lib/smarty/plugins/modifier.escape.php).
However modifying this source file does not seem to have any effect on web page. I've even added there some 'echo' instructions for debug purpose but I do not see output of these echos.
Last thing I've done was changing name of this file to: modifier.escape.php.old that also does not make any effect - escapes in templates still works fine

Does it mean that my cmsms is using Smarty from host instead of this one that is in cmsms/lib/smarty directory?
What should I do to change this modifier implementation?
