 * I get this Fatal error after updating to 3.0.4:
 * Fatal error: Call to a member function add_rewrite_tag() on a non-object in /
   home/newbaby1/public_html/wp-includes/taxonomy.php on line 289
 * This is the line in question but I haven’t a clue what is wrong with it:
 *  $wp_rewrite->add_rewrite_tag(“%$taxonomy%”, ‘([^/]+)’, $args[‘query_var’] ? “{
   $args[‘query_var’]}=” : “taxonomy=$taxonomy&term=”);
 * Can a techie person help me out please..

 * Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem? If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the Twenty Ten theme to rule out any theme-specific problems?
 * – [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? Sometimes, an apparently inactive plugin can still cause
   problems.

 * Thanks – I binned the idea of updating after trying a manual update, which didn’t
   work either – so I reinstalled my older version and everything is now reinstated.
   Don’t think I will be updating for a while…
