@Yasminelewa - please open this page in customize and check all settings, you will have option in it, if you find it difficult then I can check it on your site
Hi Yas,
First off, open your theme for customization using the customize button. Once you have it open look at the top of the left hand control navigator for your theme title, to the right of the title you’ll see three little dots, click those and from the drop down choose “Edit Languages”. That’ll bring up a new interface in the larger left hand portion of the screen, in there you’ll see controls for changing the default words the theme uses as placeholders or identifiers. There should be a search bar where you can type in “Heading” and that should bring you to the label that is being used in that footer section. You might be able to also type in Button Label but my gut is telling me that’s part of the section of your theme for blog posts, go back to the customization of your theme and look for the blog module in the left hand control navigator and see if there’s a button option in the blog module, you can just delete the button label and the button should go away.
Good luck.
