Wordpress LScache Plugin: A quick fix to whoever got a broken page in v3.5
Last Updated on: Wed, 15 Apr 2026 00:00:02 The cause is v3.5 used a different way to optimize JS. If you have JS optimize (combine/defer), and you previously had Exclude jQuery option, and in v3.5 you see a console error in developer tools: Uncaught ReferenceError: jQuery is not defined, which means you still need to exclude jQuery from combine and defer. To do that, simply append jquery.js jquery.min.js to JS excludes and JS Deferred Excludes in Litespeed Cache>> Page Optimization >> Tuning Settings.
