Reply To: Header Builder doesn't save

Hello,

First please deactivate all the 3rd party plugins except the theme required plugins then check the issue, if still the header builder not work and do not save the changes then it means all AJAX requests are blocked by your server https://gyazo.com/9b745bee4660405957ec4aa37017460a

You should contact your hosting provider to check and solve the issue from your server.

Best Regards.
