Somewhere in the last few month, you made a change in your folder structure, when exporting a website. The favivon.png and webclip.png are now in a folder called “icons”. Prior to this change, they were located in the “images” folder.
But this is a problem when hosting sites on our own server, because you can’t have a folder called “icons” on an appache server. A very easy fix would be to name the folder “favicons” on export.
