 * Hi, My ISP & I are trying to troubleshoot why my blog ([http://www.linickx.com/blog](http://www.linickx.com/blog))
   died; I know it’s not a theme or plugin thing as the admin page ([http://www.linickx.com/blog/wp-admin](http://www.linickx.com/blog/wp-admin))
   doesn’t work. (It’s wp version 1.5.1.3)
 * Now I’ve had the following e-mail from my ISP

    I have been looking into your script problems today, i have spent a 
   lot of time looking at it. First i thought it was a problem with MYSQL, i then
   ruled that out, and managed to find a certain line of code in the wp-blog-header.
   php that worries me. It seems that the header file forces a 404 error until a
   certain criteria is met, and the criteria is something to do with rewrite rules:`//
   If we match a rewrite rule, this will be cleared. $error = '404';
 * // Fetch the rewrite rules.
    $rewrite = $wp_rewrite->wp_rewrite_rules();
 * If you ask me, i don’t think it’s the best way to code a script, it
    would be
   more useful to display an error message, rather than force a 404 error. If you
   could contact wordpress, and ask them what re_write rules need to be enabled,
   i will be happy to review them, and install them if necessary.
 * I am sorry for all the trouble you have had with this, but we are as
    desperate
   to solve it as you.
 * Let me know if you need anything else

 * I’ve had a search, & codex says mod_rewrite is optional, so I’m confused.
 * Can the ISP config of mod_rewrite cause the wp .htaccess file to break & force
   a 404 ?
 * Thanks in advance.
