I cannot upload files in WP 2.7+, but this has worked before!
I get no error at all, but the file does not upload to /uploads folder.
I have tried without success to:
1. chmod 777 uploads/ (recursively)
2. Add the .htaccess "hack" to the WP root folder.
3. Switch to the HTML file upload instead of the flash uploader.
Maybe is this some sort of plugin incompatibility?
