In Site Configuration -> More Like this I see taxonomy, though I had disabled MLT Taxonomy.

Steps to reproduce:

  • Completely uninstall MLT and its providers
  • Enable MLT and MLT Taxonomy provider modules
  • Disable MLT Taxonomy module
  • Go to Administer -> Site Configuration -> More Like This -> Taxonomy
  • You will see an error: warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'morelikethis_taxonomy_settings' was given in /.../includes/form.inc on line 371.
