The 4 upload icon links have now been replaced by a single icon link to the Media upload.
I know it. The upload iframe are not showing. Maybe is some related to thickbox! Someone had the same problem?
It’s working fine for me. Have you tried:
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the Twenty Eleven theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
– re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress beta1 18972.
Deactive plugin: done (dont work)
Twenty Eleven: done (dont work)
Resetting plugin: done (dont work)
Re-upload: done (dont work)
I did all with clean browser cache. Dont work eather. I used chrome, Firefox and Safari. Dont work on then.
(sorry my poor english)
I have noteced that this file
wp-includes/js/tinymce/tiny_mce.js?ver=345-20110918
loads very slow.
Found. I was nginx cache. Just clean it.
