I am newbie to wordpress. I am trying to install multi-site. The problem I have is about adding another site to network. I've installed main wordpress, enabled multi-ste network and everything looks fine. Next I want to add another site, so I go to "Sites" -> Add new then configure path and everything. And here I've got a question. I suppose the sub site should be installed in database with new prefix ('wp2_' or something) or maybe I should just use existing prefix 'wp_'? I've looked in the database, it have created tables with prefix 'wp_2_' by itself and few other tables with prefix 'wp_' for multi blogs configuration. Everything I have in the second site administration page are errors of establishing database connection:
Error establishing database connection
till stuck with this message, then check that your database contains the following tables:
If I look in the database, these tables exist. So I don't understand what I am doing wrong. I can't find any information in the documentation specifically about adding new site, just about configuring multi-site mode.
