aliens on ""Cannot redeclare class Walker_Page" error on fresh install"

Hey,

I've been trying to move my website from localhost on my VPS, but I kept encountering the "Cannot redeclare class Walker_Page" error. I've tried the different methods described in similar posts but didn't managed to fix it.

I decided to try a brand new 3.5.2 fresh installation with an empty database. I configure the database connection details, then, when I hit the "Run Install" button, I get the same "Cannot redeclare class Walker_Page" error again.

The VPS is running Nginx as a reverse proxy for Apache with the FastCGI PHP handler and APC installed, if that's any help.

Cheers!
