I have all the media files uploaded in WP in the MEDIA content. I can see them via FTP also. When I tried to use this files in one page, an I press the option MEDIA (tw options upload new files o Media library) the media library looks empty, with no files. Some days ago the system works fine. I dind´t setup any plug in.
I Have the enfold, WPML, and the backup plugin. Those plug ins was installed at the beginning.
We only activated the WPML MEDIA , we deactivated this option an the problem still.
Can be a path corruption?

Yes, maybe there’s a database error and wordpress can’t read the corrupt data anymore. You can try ro switch to the default theme (TwentyTwelve). If the error still persists it’s definitely a wordpress problem and I’d recommend to restore the database with a backup file (sql file).
