I want to create multiple websites but with one database only. I meant that I just need to update content to one website and they are automatically update to other websites. can some one show me how? Thanks a lot
Change the database prefix. For example my database prefix might be demo_ change it to Real_. Get what I am saying
That's called multisiting, and should be dealt with depending on your exact needs. Some CMSs, like Drupal, allow it out of the box. It may work both with single database, and with different databases, depending on setup.
