Hello, Pit,
Have you installed a caching plugin or any other plugin that provides additional minification or optimization? Have you made any changes to the settings of existing plugins?
In order to troubleshoot the issue you are experiencing, we suggest that you first try disabling all third-party plugins (including cache plugins) that are not bundled with XStore. You can refer to the following link for a list of included plugins: https://xstore.helpscoutdocs.com/article/36-included-plugins . Additionally, please clear the cache of your browser and check again. It is possible that one of the additional plugins is causing the problem.
Also, temporarily disabled CDN and check then.
Kind Regards,
8theme team
