 * Here is the problem:
    I made my theme , and at the and I wanted to add “Featured
   Image” possibility and I add these two lines in my functions.php
 *     ```
       add_theme_support( 'post-thumbnails' );
       set_post_thumbnail_size( 649, 245, true );
       ```
   
 * After that when I try to update some post and click update , it takes me to post.
   php but blank page.
    Then I tried to delete these to lines but still don’t working.
   It’s same to options.php > BLANK
 * Here is my functions.php
    [http://pastebin.com/ZmzgMicM](http://pastebin.com/ZmzgMicM)
 * And here is the blog

 * How did you fix it? I have exactly the same problem
 * These are the lines I added
 *     ```
       <?php
       if ( function_exists( 'add_theme_support' ) )
       add_theme_support( 'post-thumbnails' );
       ?>
       ```
   
 * I’ve also tried to deactive the new plugins I’ve added lately and restart all
   plugins via ftp with no success
