# Fragmented cache stopped working

 * I have a couple of areas which need to be loaded dynamically and they were working
   fine up till some days ago. I updated to version wordpress 4.1.1 recently (I 
   am not saying this is the cause, but this is one of the few things I remember
   changing), and the parts that are supposed to be left out by the page cache and
   loaded dynamically are not changing with each refresh.
 * I checked that I have the `W3TC_DYNAMIC_SECURITY` defined in `wp_config.php` 
   and the parts where I want the dynamic parts to happen are defined as follows
   in my template code:
 *     ```
       <!--mfunc <?php echo W3TC_DYNAMIC_SECURITY; ?> echo adrotate_group(1);-->
       <?php echo adrotate_group(1); ?>
       <!--/mfunc <?php echo W3TC_DYNAMIC_SECURITY; ?> -->
       ```
   
 * I also checked that the Page Cache is set to Disk: Basic and that the Late Initialisation
   flag is checked.
 * I tried numerous times to turn these settings off and then on again, clearing
   all the cache in between.
 * Is there any way to debug this and understand what is happening?

 * Bump! Any ideas how to determine why fragmented caching stopped working?
 * I tried switching off and on various settings and unless I disable page caching
   the dynamic parts in the `mfunc` segments become static.

 * Finally I found what was the problem! HTML minify screws the `mfunc` snippets.
   If you add `mfunc` to the Ignored Comment Stems section then it works.
 * Would have been better if this was documented somewhere!
