This error message is an indication that the disk storage limit for the account has been reached.
FrontPage requires a minimum of 5MB of free space to
create a temporary file during publishing,
updating or recalculating a web on the remote server. If the disk limit is reached before those processes are completed, FP will return an error.
In order to correct this error and allow FrontPage to
have sufficient space without corrupting
your extensions, you can delete some files on the server,you may either upgrade your account or purchase additional disk space.
