Wordpress asks for FTP credentials to upgrade

Question

I have two Wordpress blogs. One is on a shared server and the other one is on a dedicated server. When I update Wordpress on the dedicated server it asks me to enter FTP details. When I Update Wordpress on my shared server it doesn't ask me to enter FTP details. Does anyone know the reason for this?

Can I trust Wordpress in this kind of situations?

Answer 1

It asks ftp credentials because wordpress probably does not have write permission on your wordpress root folder.So, it tries to put wp upgrade via FTP. In order to fix that go to your root folder of wordpress site and run;

sudo chown -R www-data:www-data wordpress
