 * Hi Support Team,
 * we have been using the WP-Optimize caching plugin for several years without a
   single problem. Currently, we would like to use the full potential of this great
   plugin and instead of the Autoptimize plugin, we would like to activate the built-
   in Minify feature in WP-Optimize for JS/CSS minification. We have encountered
   a critical issue with CSS minification on one site that we can neither explain
   nor describe exactly. I’ll try below.
 * 1. Activate WP-Optimize cache -> everything OK
    2. Activate WP-Optimize JS minification-
   > everything OK 3. Activate WP-Optimize CSS minification -> big problem…
 * The load on our VPS server shoots up several times. Our entire VPS starts handling
   a huge number of requests related to this site on which we have activated CSS
   minification. The site’s access log is filling up with requests quickly.
 * The server slowdown is so huge that we have to reboot the entire server and quickly
   disable CSS minification. Then the VPS runs fine again.
 * Websites where this happens are not significantly different from our other sites
   where WP-Optimize Minification seems to work without issue. The original Autoptomize
   plugin also works on this site without issue.
 * Does anyone have a similar experience? We are wondering how to solve this.
 * Thanks for the advice if anyone would know what to try.

 * Seems to be resolved.
 * The problem seemed to be caused by an incorrect path to an unused CSS, which 
   I kept including, however, and which thus failed to chain and kept retrying.
