No not failing the upload. It’s uploading, but not showing as a image.
I checked out the folder on the webhost server. And it was uploaded to the folder;
the upload path in the settings says:
wp-content/blogs.dir/2/files
wp-content/blogs.dir/3/files
wp-content/blogs.dir/4/files
And i have three childsites and a mainsite
I have a site on a domain in a subfolder under a subdomain.
The mainsite is running with another wp installation.
Therefore i created a subdomain and there i installed the wp multisite.
example:
domain.com -> normal wordpress installation
sub.domain.com -> installation multisite (but in the root it is a folder)
multisite folder: root\multisite\childsite
I tested through XAMPP localhost with WP multisite installatie and with same idea. It get’s uploaded.
