I was getting a database connection error and I checked all my settings from my host against my config file and everything looks fine. I ran the auto repair and it didn't fix it. It gave me these to copy and paste here:
wp_posts: Incorrect file format 'wp_posts'
wp_comments: Incorrect file format 'wp_comments'
wp_options: Incorrect file format 'wp_options'
wp_postmeta: Incorrect file format 'wp_postmeta'
wp_term_relationships: Incorrect file format 'wp_term_relationships'
Please help!
