So you’re upgrading a Plugin, a Theme or the WordPress Core. Thanks to the built-in upgrade function it’s a piece of cake for most of us. But have you noticed that on some installations WordPress will ask for your FTP credentials, while on others it doesn’t?
I certainly have, and I wondered how this could be explained. I have installations on the same server that behave differently, so it can’t be a server issue. It must have to do with the way WordPress was installed (Fantastico installs don’t ask for credentials, whereas manual installs do).
More to the point: how can we avoid this from happening? Let me share my findings with you 😉
