I've tried to upgrade to 2.9.2 using the automatic update. After clicking the button, I get the usual "Downloading, uncompressing... WordPress has been correctly installed". But then when I go to the Dashboard, I'm offered the upgrade again.
Checking the source of my site, WordPress version is 2.9.1. I've tried this process a couple of times. Same thing every time.
I've never had any problems with automatic upgrades. I'm using an es_ES locale.
Any ideas where to look for clues on what's going on? Or shall I just manually upgrade and forget this glitch.
