 * Hello. I’ve seen some other posts with similar titles, but they haven’t resolved
   my issue. I’ve had a blog running successfully at [http://behindthecurtain.us](http://behindthecurtain.us)
   for a few years. Yesterday, I upgraded to 3.0.3. The upgrade appeared to work
   fine.
 * I installed a new blog for a friend yesterday. I’ve run multiple blogs with different
   database prefixes just fine, so know that works. I have a weird feeling it may
   play into this problem.
 * So after finishing upgrading everything, I went to behindthecurtain.us just to
   make sure it still worked. It did. However, right after that, the site failed.
   I see wp-cron.php executing in the log, then that does it, after that the errors
   start.
    “POST /wp-cron.php?doing_wp_cron HTTP/1.0”
 * Now I just get an error 500 establishing a database connection. I’ve verified
   the settings in wp-config.php. I can connect to the database with the mysql client,
   so I know that works. I made double sure I didn’t alter any of behindthecurtain’s
   tables when I installed the new blog. I tried a fresh copy of WordPress, both
   3.0.3 and 3.0. The error log doesn’t show anything out of the ordinary.
 * I’d appreciate any help anyone can give. I don’t know if the upgrade caused it,
   or installing the new site, or perhaps some combination.

 * Wow, I just fixed it I think. SOrry for the freakout! I kept poking around and
   found that my wp_options table had become marked as crashed. I ran the mysql 
   client and ran “repair table wp_options” It did warn me that it changed the rows
   from 13,000 something to 200 something which sort of concerns me, but things 
   appear to work. Strange. This post helped, and this guy seems to have had the
   same issue a few years ago, so maybe just one of those weird flukes:

   I hope this helps someone else and I hope my blog still works. I still welcome
   any insight. I think I’ll go back up my database again now that my heart has 
   slowed down.
