I am trying to change the image size for the Latest News Widget on my homepage and I can’t. I go to Theme Functions (functions.php) and try to change add_image_size(‘sydney-medium-thumb’, 550, 650, true) to the image size I want but it’s not letting me.
I have done this in the past and it worked, but after a theme update, it’s not letting me anymore. What can I do? I’d like the images on my homepage to be bigger.
