 * My blog is down. Earlier I changed my password but it was not changed in wp. 
   admin. I have now changed this now and no longer get Error establishing a database
   connection message but now when I try to get onto the blog I get the following
   message:
 * **Internal Server Error** The server encountered an internal error or misconfiguration
   and was unable to complete your request.
 * I checked in error logs in my hosting account and the main issues came up:
 *  line 1: host: command not found[Fri Feb 11 00:27:52 2011] [error] [client 209.85.238.215]

   Engine API version 20050606 which is installed, is newer.Contact Zend Technologies
   at [http://www.zend.com/](http://www.zend.com/) for a later version of Zend Optimizer.

 * I emailed hosting support they suggest I contact Zend and get older version.
 * I thought of using backup of the database that was made Tuesday before the site
   went down or any plug ins were added.
 * I don`t want to try anything if there are any better suggestions.
 * If anyone can help I would be grateful.
 * Thanks in advance
