   Hi!

   On my blog every time the post is auto-saved I receive the following warning:

   Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/content/u/t/e/utentehosting/html/it/wp-includes/taxonomy.php on line 2411

   SELECT object_id, term_taxonomy_id FROM wp_term_relationships INNER JOIN wp_posts ON object_id = ID WHERE term_taxonomy_id IN () AND post_type IN ('post') AND post_status = 'publish'
   
   Warning: Invalid argument supplied for foreach() in /home/content/u/t/e/utentehosting/html/it/wp-includes/taxonomy.php on line 2418

   What it all means and how can I fix it?

   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 default theme to rule out any theme-specific problems?

   Hi,

   Thank you so much for replying!

   Yes, you're right, it's the WP-dTree plugin that causes the issue.

   Thanks!

   Andrew
