Missing the icon to Open/Close an accordion in content

Hello,

This seems to be your site any third party plugin confliction issue, Your site CSS is coming from the cache, Please once check your site after deactivating all the third party plugins including cache plugins and check your site after removing the browser cache, I am sure your issue will solve and please try to check your site after flushing your server CDN cache as well: https://screenshot.net/57yo8s8 and if in case your issue will not solve then do not turn the third party plugins Activate, and share your site WP Admin Login credentials with me so that I’ll check it for you.

Best Regards.
