Hi Max
You can do this with some custom CSS! The CSS needed to remove this is
body.ls_left .head-toggle {
display: none !important;
}
Its always best to use a Child Theme for custom changes like this so that these changes will be kept safe in future updates. More information about creating a child theme can be found here https://codex.www.ads-software.com/Child_Themes
If you are having problems determining the appropriate CSS id and classes to assign the custom CSS to, check out this amazing free utility called Firebug
Firebug Guide for Web Designers:
https://sixrevisions.com/tools/firebug-guide-web-designers/
It will help you look up sections’ or elements’ CSS.
After you do the changes, make sure that you clear the cache and “hard” refresh the page in your browser to be able to see the changes right away. If you’re not sure how to “hard” refresh a page in the specific browser you’re using, just Google it and you’ll find instructions how to do that. Also, don’t forget if you have any Caching WordPress plugins installed, or use a CDN (like CloudFlare) to also either clear their cache or disabled them for the time being altogether. This site has some great instructions on cache clearing: https://www.wikihow.com/Clear-Your-Browser%27s-Cache
Hope this helps ??
