 * I have had a few problems with my blog going down.
    I now get message: **internal
   server error** The server encountered an internal error or misconfiguration and
   was unable to complete your request.
 * I have checked error logs in my hosting account and these two issues seem to 
   be recurring
 * sh: line 1: host: command not found
    [Fri Feb 11 00:27:52 2011] [error] [client

   Contact Zend Technologies at [http://www.zend.com/](http://www.zend.com/) for
   a later version of Zend Optimizer.

 * Try:
    – switching to the Twenty Ten theme by renaming your current theme’s folder
   in wp-content/themes using [FTP](http://codex.wordpress.org/FTP_Clients) or whatever
   file management application your host provides. You may need to access /wp-login.
   php to get this to kick in fully.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or phpMyAdmin.
 * – re-uploading all files & folders – **except** the wp-content folder – from 
   a **fresh** download of your version of WordPress.
