Have you ever tried to get rid of or just temporarily disable the home page slider on certain Oceanwp demo themes like the “Personal” theme template?
Ocean WP uses a slider shortcode to embed on the home page. You can find the sliders in the WordPress Dashboard column button called Posts Slider. You will see one called “Home Slider” Just go to the home page and the OceanWP Settings. Click Shortcodes in the left sidebar or the <> icon in Gutenberg Page settings. Find the shortcode and delete it.
