Seems like after moving a WP installation from one server to another I have lost a possibility to upgrade WP or install new plugins.
After I try to update, I get the message that WP needs access to FTP and asks me for ftp login and password. I type in what I am asked for but it always tells me the login/pass are wrong.
No idea where to look for the solution.
