# WordPress Table ‘*_dtree_cache’ doesn’t exist

 * On a multisite running on sub-sites, these messages are flooding the log because
   the plugin checks for a table with the main blog prefix.
 * Using `get_blog_prefix()` like this from line 1 in wp-dtree-cache.php should 
   fix it:
 *     ```
       <?php
       //In WP 2.6, I suddenly got problems with global variables "dissapearing", so these getters are... Q&D.
       function wpdt_get_table_name(){
       	global $wpdb; return $wpdb->get_blog_prefix() . "dtree_cache";
       }
       ```
   
 * Too bad the plugin does not simply use WordPress own Transient API to store cached
   strings though… Much simpler and avoids the need to create new DB tables.
