[WB20] Deploy site error (Pt.2)

Hi,

whenever I try to deploy a site from WebDev on the server via FTP, at the end of upload I get this error:

INFRegistering the site in the administrator
ERRFailure saving the application in the account file.
ERRCheck whether the permissions on the files are correct (or contact the server administrator and transmit him this message).

Does anyone know what to do?
