WordPress Manager - Discover Scan failing

Hello folks, I got an account with some WordPress sites, 4 of those are appearing in "Wordpress Manager" correctly, but two other Wordpress sites (both subdomains) are not. The "Discover Sites" option returns something like this: The system found a new WordPress site, "/home/User/SubdomainPath/wp-config.php", but could not make it manageable because of the following error: The batch response did not contain the Administrator Information. Is there anything I can do about this? I created a new subdomain and wordpress manager worked very well for it, it seems to be only for those two. Thanks.
