 * Hi,
    I have problem with w3.0, whose i never had with others version. Exactly
   sometimes wordpress lose query and didn’t get data from database (not all, i 
   have multiple loops on one home/page, and sometimes is ok and sometimes one of
   this query not running – most in the header). I run it on my localhost (newest
   Xampp). What worse I don’t have any ideas why problem occure, i can only suspect
   that its problem with global wpdb var but i’m only beginner programer. To brighten
   problem i attached two print screen.
 * Secondly, others maybe not bug but problem is that when i use get_the_post_thumbnail()
   function and i set width to 150px core load image post thumb with size 150×150
   which is in most case cut off, but when i set 149 px on width it get image 150px
   on width and well get height but not cutted off.
