I have set up two blogs to use the same database. The only changes I made to each of the wp-config.php files were to add a prefix to identify the site and I also changed the random text for the key generation.
Looking at the database I now have two sets of tables with the prefixes looking OK.
I can log in to the first site OK, but when I try to log in to the second site it doesn't recognise the username and password. The web address of the first site is then displayed in my browser bar.
Am I missing a simple step or setting?
Cheers
