You should take a look to my second database, please and then indicate me how to proceed. My place is working and it is absolutely necessary for me to increase disk space, I am without disponible space for now.In first installation of WP, it has been located on /wp.
But I did not like this directory, so I have unintalled it and then, I have install a new WP on my subdomain, without /wp. Can you check? The project is working, it isn't abandoned.
