I am trying to make modification on one of the headers using Header Builder, but it has a problem.
When I try to save the header, it keeps loading indefinitely. So no changes are actually saved. I’ve opened the console and I’ve attached a screenshot of the problem, as well as the saving process (that never ends).
We see that admin-ajax.php POST requests from our header builder are blocked somehow by your server. Contact your hosting provider and ask to investigate this particular HTTP request when you save the header data. https://gyazo.com/2e09ed354ad3e42c2ccd06af1898fef8
