I am not able to change the header logo and layout using the Header Builder. I have deactivated non-theme related plug-ins, but I still not able to change the header logo or layout. Please help.
I have uploaded the logo on your site from Header Builder and it is showing fine on the frontend as well. Please see the screenshot here: http://prnt.sc/r63lfn
When I was using an SVG format, the logo did not show up. I am using PNG instead, and it is now showing. There was no error when uploading either of the files.
To fix this problem, you need to open your SVG icons file with some editor like Sublime Text or default system text editor and add height and width attributes to your <svg> tag like it is shown on the screenshot https://gyazo.com/83fd36b0bb9628bb1aed2bd3d5d063c5
Then you will need to reupload your logo image.
