I just posted a thread about this, but it seems to have disappeared, so here it goes again.
http://ingridsblogg.no
Atahualpa 3.7.15
WP 4.1
After a WP update a few months ago the favicon disappeared. It showed sometimes, but now its completely gone. I saw in the code for the index page that the path for the favicon was to a non-existing folder. I created this folder, including a copy of the favicon, and the path now works. But the favicon still does not show where it should.
I know I should upgrade the atahualpa theme, but every time I do so I have to re-create the header area and the ad-area in the center of the blog. I therefore try do restrict the number of times I have to do this. I am aware that this could be the reason why the favicon is not showing, but now as the path to the favicon should work again, I would expect it to work (link rel="shortcut icon" href="http://www.ingridsblogg.no/wp-content/ata-images/fff-heart.ico"). I am also aware that it could take a while before everything is updated, but I did this yesterday, and it is still not showing.
Any suggestions?
