I installed WordPress at my site using my host's download program.
I logged into the Admin panel using Firefox 3.5.3 and WordPress 2.8.4, went to Media | Add New. I arrived at the Flash Uploader and clicked Select Files, which opened a browser-type window.
I selected a JPEG about 36K. The browser-type window disappeared.
A bar stating "crunching" appears for a brief moment in the Add New area. It disappears, leaving image information but no images or thumbnails. When I enter the URL for the image in a new browser window, the message 403 Forbidden appears, with "Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
The same thing happens when I try the Browser uploader.
I have checked my permissions for the folders all the way down to the file level; the permissions are set to 755 for public_html, blog (the blog subdomain and the main folder I used for the WordPress install),
and wp-content folders. The permission is set to 777 for the uploads
folder. The year/month structure folders are set to 777. I have pictures saved both in the uploads and 2009/10 folders. I have used the Settings | Miscellaneous folder to turn off the year/month structure. The store uploads in the folder option is set to wp-content/uploads (default).
The upload folder, when I view it from my host, appears to contain three images files per image, or three different sizes. The permissions for the images are all set to 666. I am able to view the images via my host.
I have deactivated all plugins and widgets; I am using the default theme. I have tried all the steps in the sticky.
Any advice?
