I keep receiving this message "Error establishing a database connection" when I attempt to do anything with my blog or admin page. It does vary though, sometimes it works sometimes it doesn't, but overall it's been very slow. I recently upgraded to WP 3.5.
I also uninstalled the most recent plugins incase that was a factor, but to no avail.
I haven't changed my password or anything, nor edited any content other than a blog post.
Here is my site: http://theroadnotprocessed.com/
I use Bluehost.
