Hi ThimPress,

Here’s the Twenty Twenty Theme conflict report to seek your attention.

1. Summary archive page conflict:
LP course page is blank.

Theme option: https://postimg.cc/wRzqF1cg

2. Full archive page conflict:
LP course page width is too narrow. Output Link attached https://freehappyglobal.com/DiaMondDriV3rs/subjects/

Please advice on the CSS or PHP of LP.

Best regards,

Mike
