Here is few steps:
- Right click on your area what you want to change/remove and inspect in console.
- Find in console HTML part what you want change/remove
- Look if have some ID or unique class.
- If you find some unique ID or class, just simple add custom CSS in your template with property
display:none !important;
- If you not find any kind of unique ID or class, try to find some parent ID or class and find in CSS right route to your element you want remove/change and add CSS property to it.
The worst thing you can do also is to go inside PHP and find that element and remove inside template or plugin.
