Theme fails to load to WordPress

The Docly WordPress Theme fails to load into WordPress. My login information for WordPress/SiteGround.com is. Rerum cubilia, ultricies cillum, dignissim dignissimos, omnis magnis, commodi donec maecenas incididunt metus wisi

The margins in this first section is huge and we are trying to reduce it so the page doesn’t have a huge empty space, but when we move the margins to -250+, the buttons in the first 3-4 rows won’t work anymore.

Please help!

Thanks
