 * I installed Zend optimizer as per
 * [https://managewp.com/boost-wordpress-performance-zend-optimizer](https://managewp.com/boost-wordpress-performance-zend-optimizer)
 * and unfortunately it breaks Custom CSS. I don’t expect you to spend much time
   on this but thought hey if it’s obvious then you might have an easy fix.
 * Cheers

 * Well no not really lol. It just doesn’t load and/or render the CSS when I have
   the Zend stuff running. I’m just setting up a new VPS and trying to optimize 
   it for WP sites.

 * Can you post a link to the site you having the problems on?
 * If not, can you view the source code of your page and find the (custom css) link
   the plugin creates, and then open that in your browser and let me know what happens?

 * Hey Peter,
 * I’ll try that a bit later and let you know. I’m in Toronto so it’ll be tomorrow
   for you 🙂

 * The link was in the source and I clicked through to the css file and it’s all
   there. I found that if I disabled Quickcache it fixed the issue. I’ll try super
   cache and see if I get the same thing. Although the speed gain on the Zend might
   negate using a caching plugin.
 * Thanks for the help!!
 * Cheers,
