I want to remove the sidebar from the itinerary site when I chose no sidebar in layout it doesn’t work sidebar keeps showing up. I toke a look at theme editor, and think this part is not working;
in file: wp-travel/archive-itineraries.php
The page layout depends on the theme that you are using. If you have used the Travel Log theme then it does have the option to manage the layout. For this, you need to go to the page and chose no sidebar option.
Also, if the theme have not provided the option then it can be removed using the CSS.
So please provide your site URL so that we can help with the CSS.
