Can’t seem to change my website content

Nobody can see your screenshot here, you would have to provide it as described here: https://www.ads-software.com/support/forum-user-guide/block-editor/#adding-screenshots

However, I can see that you are using Elementor to edit your page. I would therefore recommend that you contact their support forum: https://www.ads-software.com/support/plugin/elementor/

The marked location is output via the MyTravel theme you are using. As this is a commercial theme, I would ask you to contact their support: https://themeforest.net/item/mytravel-tours-hotel-bookings-woocommerce-theme/38921960/support – questions about commercial products are not permitted here in the forum.
