# Litespeed Cache – Load CSS Asynchronously breaks FS

 * Hello,
 * Firstly I would just like to say what an amazing little plugin this is, I only
   discovered it a few days ago, what a gem, can not believe I never found this 
   sooner, excellent work!
 * Unfortunately though I’m not just here to blow smoke up your rear, today I have
   found that the function of your plugin does not work with the Litespeed Cache
   option enabled – “Load CSS Asynchronously”.
 * I have disabled and re-enabled the “Load CSS Asynchronously” option many times
   before posting here “just to be sure”, every time I enable it the delay is removed
   and scripts load as they would without Flying Scripts enabled.
 * I hope I have explained clearly, if you need more Info from me please ask. Any
   tips how to resolve this issue will be very much appreciated. P.s. Just to be
   clear I am not using CSS/JS minify combine options at this time.
 * Best regards
 * Lee

   We have seen customers using Flying Scripts with LiteSpeed cache’s Load CSS asynchronously.
   It could be something specific to the site.
 * Without URL, I’m unable to debug.

 * Thank you for clarifying, I have disabled the option for past 5 days, the issue
   has not returned. I will try again in a test environment to see the outcome.
 * One other thing, I have noticed the following in my server error log. (IP and
   URL omitted) Should I be concerned ?
 * [NOTICE] [100428] [162.*.*.*:61358:HTTP2-1#mydomain.com] [STDERR] PHP Warning:
   strpos(): Empty needle in /home/mydomain.com/public_html/wp-content/plugins/flying-
   scripts/html-rewrite.php on line 7

 * Hello,
 * I removed some line spaces, that seems to have resolved the notices!
 * Thank you
