Wordpress
From charlesreid1
Getting tired of fixing this problem over and over.
Solve FTP problems
install/run vsftpd on Unix
change /etc/vsftpd.conf to include the following line at the end:
listen_port=21
You could also change the port number that Wordpress uses.
Once that's done, and you go to update something in Wordpress, you can give it your usual login credentials (your Unix username/password) and everything should work.
If not, you may have a permissions problem with your server - wherever Wordpress is trying to install its extensions or updates. In that case, use chmod/chown to change ownership of your Wordpress content folder:
sudo chown -R charles:charles /www/wordpress/wp-content
