We have an active WP blog, but are building (in a different folder) a new design for our blog using CE. I dowloaded CE, then created a CE-child theme to work in. When I try to change the header by uploading an image from my computer, I get this message – “The uploaded file could not be moved to wp-content/uploads/2015/08.”
Via ftp, I created this folder (in CE-child) and manually moved the image into it. But the image still will not upload.
The source code says the header image path is <div id=”header-image”>

</div>
Should the path be in the CE-child folder? How do I make this work?
I did not have a problem with changing the header image until we had our web host copy the database into our new, trial blog folder, so we could work with the content and see how to design.
Did copying the database somehow affect the ability to upload images/change header?
