 * Check the “Http/2 push CSS” option
    Then WooCommerce related pages return 503
   Uncheck the http/2 push, then everything is back

 * Hi,
 * I believe this is more of OpenLiteSpeed issue instead of LiteSpeed Cache plugin
   issue.
 * Please try [upgrade](https://openlitespeed.org/kb/how-to-upgrade-openlitespeed/)
   OpenLiteSpeed to latest version 1.6.10 and see how it goes.
 * If it still gives you 503 error, please submit ticket to [litespeedtech.com](https://store.litespeedtech.com/store/submitticket.php)
   as that is a more appropiate channel for OpenLiteSpeed related issue.
 * Best regards,
