# mfunc not working – PgCache.php not running wp-config.php?

 * I’m trying to get mfunc to work. So, I have set a value for “W3TC_DYNAMIC_SECURITY”
   in wp-config.php.
    However, I’ve discovered that the PgCache.php does not get
   a value for “W3TC_DYNAMIC_SECURITY”, so it thinks all cached pages are non-dynamic,
   and __parse_dynamic() always returns without trying to replace dynamic code.
 * It appears that wp-config.php isn’t being loaded each time PgCache is called —
   my testing output log shows this — so that’s why mfunc just won’t work!
 * If I add
 *     ```
       define('W3TC_DYNAMIC_SECURITY', 'mySecretCode');
       ```
   
 * inside of the _parse_dynamic() function in PgCache.php, my ‘mfunc’ code works.

 * This is a real big problem…with the above fix, W3TC starts parsing the code between
   the mfunc tags. However, now I see the second issue — you use an “eval()” and
   your code will only work with PHP code in the mfunc, not HTML code.
 * AdRotate inserts HTML text, not PHP. That means AdRotate won’t work with the 
   caching.
 * Argh!!!! What to do?
