 * I spent several hours running down a problem that occurred when I selected the
   CSS Minify option. The Litespeed caching plugin was looping and finally failing
   with a 500 “internal server error” after it exhausted all available memory (at
   line #515 in the lib/css_min.class.php file). I finally found the issue to be
   a missing trailing right brace “}” on the last line of a CSS file. I was able
   to find the error through the debugging option and identified the last CSS file
   processed. The CSS error in Elegant Theme’s CSS file has been corrected, but 
   I wanted to give you a heads up on the processing side-effect of the missing 
   brace.
