I am seeing this issue too. Right now I don’t have access to FTP behind the WP instance, so I can’t check whether WP_DEBUG is set to true in wp-config.php or not.
I just need a way to get files off the WP instance concerned so I can migrate it all to a new server for a client… I thought Cysteme would be a useful tool for this situation… looks like I am stuck and will have to work on getting FTP access to the “old” site.
