Same problem here, very-very frustrating. I’ve posted this:
Unfortunately, I’ve posted it in the wrong board, however, a reply of Bill_S (thanks Bill):
"However, be that as it may, you cannot update to a later version of Wordpress. The application, as is, is what you get.
Now, concerning the fatal error that you received, I will have it looked into. Someone may contact you for more information. If you could help them it would be appreciated."
No updates of Wordpress? Why isn’t that possible? Security? New functionalities? I really should have bought an external disk or a real NAS.
