 * I’ve been having some weird problems with one of my 2 blogs that I’m not having
   with the other and I’m not sure how to go about troubleshooting them.
 * Both are running 2.7.1, but one is failing in a number of processes while the
   other functions just fine. Both are on the same host server but use different
   databases.
 * For some time now (I can’t say exactly when this started) my automated plugin
   updating has been broken. It gets to the point where it says that it’s downloading
   the plugin, but then no browser activity takes place and nothing progresses beyond
   that point.
 * Automated WP upgrading also seems to be broken, I have no upgrade to perform 
   right now but I’ve had to do the last couple iterations manually.
 * Those are annoying, but the REAL PROBLEM is this:
    Every single time I post up
   a new entry, it posts just fine but I’m thrown to an Error 500 page:
 * “Error 500 – Internal server error
 * An internal server error has occured!
    Please try again later.”
 * This provides absolutely no useful debugging information, so I have no clue how
   to even take a wild guess as to where the problem might lie. Somewhere in my 
   code? My plugins? My webserver? My database server? (My webhost was having server
   issues a little while back and I’m just assuming that they sorted them out ’cause
   I stopped getting the public errors across all my sites that were associated 
   with that.)
 * Apparently quickposting doesn’t trigger this error page, only full posting. Just
   realized that.
 * Furthermore, posting a comment just now gave me this error:
 * “Lost connection to MySQL server during query on line: 546”
 * Line 546 of…….??? Beats me.
 * So… anyone able to even tell me what questions I need to ask to start figuring
   this out?

 * I see 3 likely possibilities
 * * you need to run a repair on your database tables with phpmyadmin
    * you need
   to deactivate all plugins and test to see if one is causing you grief * Your .
   htaccess is whacked – delete it and reset permalinks admin – settings – permalinks
