I know Woodmart’s demo sites are all subsites. All of the logo links in the header are pointing back to the main site. In my case the logo links all point back to the homepage of the specific subsite.
I guess my question is beyond theme support but I hope you will make an exception and help me out. What did you do to make all header logo links point back to main site? Did you install a plugin or did you add a snippet to functions.php? I was searching for a solution but can’t find it on the internet. I hope you can provide me the snippet or an answer.
Our demo doesn’t use WordPress multisite option. So in your case, the only way to solve it is to customize a logo element in a PHP file and hardcode a link to your main website.
