 * Custom functionality has been created around mfunc and the option referenced 
   in the Advanced Settings page to enable dynamic content is greyed out. The condition
   referenced in the plugin’s code to cause the setting to be inaccessible don’t
   seem applicable. How can we be sure that the mfunc tag for dynamic content can
   function while running 1.3.2.

 * You have to set caching to PHP mode, I forgot to add that to the settings page.
   🙁
 * Unfortunately mfunc is going to disappear in the next release, to be replaced
   by something much better and safer, a filter using your own tags. It’s not backwards
   compatible and works in a completely different way.
 * Check out the post and my comment [here](http://ocaoimh.ie/y/5a) for more info.
   You should *definitely* download the development version or svn export from trunk(
   link in the comment) and try it on a test server. There’s an example plugin with
   documentation describing what it does. Any feedback would be really appreciated.

 * We are currently using legacy mode, could this still work? We understand that
   this will be removed, but anytime we can buy to develop another means to achieve
   the custom functionality based on it will help.

 * Remove this from line 983 of wp-cache.php:
 * `<?php if ( $wp_cache_mod_rewrite || $super_cache_enabled == false ) { echo "
   disabled='disabled'"; } ?>`
 * The checkbox should no longer be disabled.

 * Thanks! That’s the line we found. We didn’t want to edit the plugin files if 
   we didn’t have to.
