Used the advanced options header section and pasted the snippets code for a header logo. Showed up fine. Tinkered a little to see if I could get it aligned left instead of center and it disappeared.
I have deleted everything from the header section and then re-pasted. Deleted the logo jpeg and re-uploaded to the media library and updated the snippet. Still no logo in the header.
Also - the page doesn´t show at all in Explorer (I use Firefox)- only the gradient background. Any thoughts?
