 * mfunc doesn’t work. You use a secret code only for a “mfunc”. And not for a closing“/
   mfunc”. Now I turned off W3 Total Cache support and use next code instead of 
   AdRotate widget:
    <!– mfunc secret_code –> echo adrotate_group(2); <!– /mfunc
   secret_code –>
 * For a standard Text widget it need to remove line breaks to prevent an eval error.
   So it will looks like:
    <!– mfunc secret_code –>echo adrotate_group(2);<!– /mfunc
   secret_code –>
 * Also when mfunc doesn’t work impressions work for the dynamic mode only. For 
   the standard mode impressions count one time (before a page will be cached). 
   With the mentioned above solution mfunc and impressions work fine.
 * AdRotate 3.14 free.
    WordPress 4.3.1

 * I’ve followed the manual and had some trial and error to get the current implementation
   working.
 * If I change it to what you say, W3TC gives errors about things not being set 
   up right. The current method works for me and many others.

 * My suggestion works only for the text widget and themes templates. If just add
   a secret code to “/mfunc” in adrotate-functions.php and adrotate-widget.php it
   shows an eval error. I didn’t learn yet how to solve it.
 * If I’m not mistaken “/mfunc” without a secret code doesn’t work since WordPress
   4.1
 * Anyway I have notified you.

 * [@arnan](https://wordpress.org/support/users/arnan/),
 * This is the error message from W3TC PgCache.php. Please look at the format.
 * “Invalid mfunc tag syntax. The correct format is: <!– W3TC_DYNAMIC_SECURITY mfunc
   PHP code –><!– /mfunc W3TC_DYNAMIC_SECURITY –> or <!– W3TC_DYNAMIC_SECURITY mfunc–
   >PHP code<!– /mfunc W3TC_DYNAMIC_SECURITY –>.”
 * I have found the way how to solve the error which you got with implementation
   this correct format.
 * For example, for the adrotate-widget.php the code should looks like:
 *     ```
       if($adrotate_config['w3caching'] == 'Y')
         echo "echo adrotate_group(".$instance['adid'].", 0, 0, 0);";
       else
         echo adrotate_group($instance['adid'], 0, 0, 0);
       ```
   
 * For the adrotate-functions.php
 *     ```
       if($adrotate_config['w3caching'] == "Y")
         $output .= "echo adrotate_group($group_ids, 0, 0, 0);";
       else
         $output .= adrotate_group($group_ids, 0, 0, 0);
       ```
   
 * The same way for the call **adrotate_ad** function.
