Hi there!

Thanks for your query.

Can I have your site URL here, please?

However, here is sample code for you, that need to be entered within the custom CSS:

.sppb-addon-article .sppb-article-info-wrap> h3 > a{
    display: none;
}

Note: Path towards custom CSS: Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.

Hope this helps anyways.

Best Regards
