i already install sitemap generator plugin by arneebrachhold.de. and activate it, but how to use it? when i try mysite.com/sitemap.xml i got 404 page not found
Manually create a html file, a blank one. Save it. Rename it to sitemap.xml upload in your public html then. Make that sitemap xml writble by the server through ftp or cpanel file browser. Go to manage or settings in your wordpress admin/dashboard, select the TAB sitemap config, then manually make a sitemap, (you should see button there to do this with one click). Then try it and everything should work. Cheers.
