With my site I tend to make a few (3-5) posts at once. But almost always, the site slows down, and I get the error "error establishing database connection" after hitting publish.
I use cloudfare as the CDN with caching enabled & html/css/js minify. i have deleted 6000+ rows of post revisions, and i have WP Super Cache enabled. My host is bluehost.
why do i have so much trouble making multiple posts?
