Title: Missing after enable “Optimize JavaScript Code” + “Aggregate JS-files” Last modified: October 5, 2018 --- # Missing after enable “Optimize JavaScript Code” + “Aggregate JS-files” * Resolved [sammyhk](https://wordpress.org/support/users/sammyhk/) * (@sammyhk) * [7 years, 7 months ago](https://wordpress.org/support/topic/missing-after-enable-optimize-javascript-code-aggregate-js-files/) * Thank you for your great work. * After upgraded to Autoptimize 2.4, we found enabling “Optimize JavaScript Code” + “Aggregate JS-files” will cause the generated HTML missing end tag. This cause “WP Super Cache” plugin not working. Actually we suspected after Autoptimize 2.4 upgraded, “WP Super Cache” keeping not caching any page. After enabled the“ WP Super Cache” debug log, it show “” in the generated HTML. When we disabled“ Aggregate JS-files” in Autoptimize, the HTML return normal and “WP Super Cache” works again. * Please help to fix this issue when you have time.
