Hello, I just want to let it out there that the following feature disabled our guest users to use Accordion functions and certain checkout plugins from being load up, this happened right after WordPress 5.5 update.
Defer Render-blocking JS
Defer loading of render-blocking JavaScript files for faster initial site load.
It could be due to the fact that Jquery-migrate was removed by WordPress, I got the email today from WordPress for a temporary fix:
https://wordpress.org/plugins/enable-jquery-migrate-helper/
The problem was successfully fixed after disabling this from SG Optimzer plugin.
Thank you.
