I have the hotel booking plugin and the booklium theme running. When inspecting the site I can see that jquery-migrate v361 is loaded. I thought this is no longer supported/outdated. Is this still needed for booklium or the hotelbooking plugin or can I get rid of it? regards
Starting from WordPress 5.5 jquery should no longer be loaded. WordPress 5.5 was released in 2020 almost 3 years ago. Can you please work to remove that code that wordpress has long decomossioned from your datepicker.
