Hello there,

Thank you for getting in touch.

Try changing the header image in the page header meta box settings as shown in this screenshot. We have a guide on the same here https://themenectar.com/docs/salient/page-metaboxes/.

You can also check if you have created the header using the Nectar slider plugin and see if you can fix this from there. We have a guide on the same here https://themenectar.com/docs/salient/nectar-slider-plugin/.

Try this and let us know if you need further assistance with this.

Kind regards,
