What could I do? The blog I need help with is daydaysmile.wordpress.com. Sep 30, 2017 at 3:30 am #3026846 rosepajarojaStaff Hello @daydaysmile, I tried this theme – Dyad – and tested the header image and it works fine on my end. I tested both using the images provided and uploading my own image. See it here – http://rosepajarojavolunteer.wordpress.com Please note, while you can crop images to your liking after clicking Add new image, your theme recommends a header size of 1800 × 720 pixels. Do you get an error message? Do you follow the instructions from this link? Regards, Rose Author Posts The topic ‘Theme header not work’ is closed to new replies.
