I'm having issues with images in Wordpress 4.6.1. I have read numerous threads and there is no questions or solutions which are relevant to my issue (that I have found).
I have found the issue is related to the resizing mechanism. The full sized image loads fine, but the resized images, including the thumbnails in the media library fail with a 404 error. For example here is a link:
Media library thumbnail URL (not working):
Full size image without the dimensions as part of URL:
This is a new installation and I have all plugins disabled. I have verified the images are there (obvious as the normal size image loads). I also have another site on the same server, I have temporarily removed its .htaccess file and no difference was made. It also is not a caching issue as I have tested it with caching disabled. I'm also running php 5.6.x and gd is enabled.
My number one hunch is related to the resized image code. I'm assuming a folder is used to store the resized images (to avoid on the fly generation of the same image). I cannot find this so I think this may be my issue.
Does anyone know if a storage location is used for generated thumbnails/resized images?
If so, what is the name and location of this folder?
If it is not being created due to permissions or other issue, at least I know where to start looking. Of course, any other pointers or help is appreciated.
