I ran through the Network Activation process based on the instructions on my wordpress site. When I modified the .htacess and wp-config files, I cut and pasted the code from my wordpress site to avoid errors. Having done that, I now get an error when I try to go to the site: "Error establishing a database connection." When I try to go the admin page (/wp-admin), I get the following message: "One or more database tables are unavailable. The database may need to be repaired." Can anyone tell me what I'm doing wrong?
