Ich habe ganz viele php Fehlermeldung bekommen mit dem Hinweis "Duplicate entry ..":

Location http://localhost/drupal6/admin/settings/swftools/handling
Referrer http://localhost/drupal6/admin/settings/swftools/embed

Es gab viele verschieden Messages ich poste mal zwei verschiedene:
Message Duplicate entry 'admin/content/taxonomy/%/add/term' for key 'PRIMARY' query: INSERT INTO menu_router (path, load_functions, to_arg_functions, access_callback, access_arguments, page_callback, page_arguments, fit, number_parts, tab_parent, tab_root, title, title_callback, title_arguments, type, block_callback, description, position, weight, file) VALUES ('admin/content/taxonomy/%/add/term', 'a:1:{i:3;s:24:\"taxonomy_vocabulary_load\";}', '', 'user_access', 'a:1:{i:0;s:19:\"administer taxonomy\";}', 'taxonomy_add_term_page', 'a:1:{i:0;i:3;}', 59, 6, 'admin/content/taxonomy/%', 'admin/content/taxonomy/%', 'Add term', 't', '', 128, '', '', '', 0, 'modules/taxonomy/taxonomy.admin.inc') in U:\Asus-Ursprung\xampp-asus\htdocs\drupal6\includes\menu.inc on line 2443.

Des Weiteren findet der flowplayer die Flashdatei nicht. Sondern gibt folgende Fehlermeldung aus:
200, Steam not found, NetStream.Play.StreamNotFound, clip :'[Clip]'htpp://localhost/drupal6/sites/default/files/sites/default/files"

Zwei mal wird der Pfad angegeben!!

Wie löse ich das?
