Some of the files and directories in my home directory became "invisible". The home directory is encrypted with Ecryptfs. The files and directories are not hidden. Permissions and ownership are set correctly. The items don't show up in any file manager, nor with the "ls" command. However, they can be accessed as long as I know the name. For example, the directory "Documentos" can't be seen, but I can enter it using "cd Documentos". Inside subdirectories, everything works fine.
