Hello, Dear Al Vidovic!

If you want to replace background in breadcrumbs area, just replace image features.jpg in /wp-content/themes/ecoroofs/img/parallax/ on your own. The new image would have the same name as features.jpg It's recommended size is 1920 x 1272 px.

If you want to hide completely this area, click WP Dashboard => Appearance => Customize => Additional CSS and insert here the following code:

.page_breadcrumbs.parallax {
    display: none;
}
.section_padding_top_100 > [class*="container"] {
    padding-top: 50px;
}

Then click "Publish" button.

In this case please provide us with the following info:

1. Link/login/password for your cPanel or similar hosting control panel.
2. Link/login/password for your WP Dashboard.

We strongly need exact information about this both points, only in this case we will be able to help you.
