I installed the Reader and Post Indexer plugins today and also added Avartar for Multisite and Site Search plugins. I also fully activated Anti-Splog for my network by entering the API from my WPMUDEV membership area. My network has been working fine but now it sometimes gives this error "Error establishing a database connection" or
"Can’t select database
We were able to connect to the database server (which means your username and password is okay) but not able to select the blog_wrdp1_global database.
Are you sure it exists?
Does the user siteuser_wrdp1 have permission to use the blog_wrdp1_global database?
On some systems the name of your database is prefixed with your username, so it would be like username_gbblog_wrdp1_global. Could that be the problem?
If you don't know how to set up a database you should contact your host. If all else fails you may find help at the WordPress Support Forums."
I deactivated the Reader, Post Indexer and Avartar for multisite plugins, but the error still remained. I have activate the plugins because I need them on my network. Can someone please tell me why I am getting these errors and what I can do to fix it?
