Title: 404 Error with CSS Last modified: September 18, 2021 --- # 404 Error with CSS * [michaelsmartmove](https://wordpress.org/support/users/michaelsmartmove/) * (@michaelsmartmove) * [4 years, 9 months ago](https://wordpress.org/support/topic/404-error-with-css/) * Hi, * I am currently experiencing CSS loading issues with the Litespeed Cache plugin. * It seems to have cached the path to a specific CSS file (combined CSS file) which doesn’t exist anymore. * In the browser console (Firefox & Chrome) it gives me a 404 error for the CSS file. * As per your documentation ([https://docs.litespeedtech.com/lscache/lscwp/ts-optimize/](https://docs.litespeedtech.com/lscache/lscwp/ts-optimize/)), I’ve appended /?LSCWP_CTRL=before_optm to the website URL and then the website loads as intended. * When I then purge the cache the website loads again like normal. * Here are screenshots of the website and browser console: Browser Console: [https://imgur.com/a/6RsPvyr](https://imgur.com/a/6RsPvyr) Website: [https://imgur.com/a/ME7C30z](https://imgur.com/a/ME7C30z) * I’ve submitted a report to Litespeed. Here is the report number: Report number: RJLFNJHL * Your assistance in this matter is greatly appreciated. - This topic was modified 4 years, 9 months ago by [michaelsmartmove](https://wordpress.org/support/users/michaelsmartmove/).
