For what it’s worth .. I’m trying to develop my website locally and I’m getting the same problem. Most of these posts are way over my head but I do have an operational copy of the site running on 1 machine and the other “corrupted” version that won’t connect to the database. I running instant wordpress. I’m using a difference tool to examine the files between the operational and defunct versions. My problem is repeated and intermittent – I have compared WP-CONFIG.php ; FUNCTIONS.PHP ; and WP-CRON.php – the are identical. Is there another comparison that I may make that might help. It’s starting to look like WordPress is useless and I wasted a lot of time. Thanks for everyone’s input
