My website http://www.weegiewednesday.org
I want to change the Header Image.(it is on all pages)
I tried settings/general and Appearance/customize.
I also Googled and found various tips-
Seems I need to locate the theme's style.css or the header.php file
I have no idea where these files are or how I can access?
The site was set up by someone else and I am trying to update it.
Any simple solution please?
I don't even know what Them this is.
I don't know what version the site is either
Would appreciate help
