Answer 1

Hey guys, I found THE solution.

Problems :

• Custom field display twice.

• No Ajax/jQuery visual feedback.

If you've been working on the file function.php, make sure you remove extra line breaks.

Particularly at the top and the bottom of your file... If you have some line breaks, your xml got an error : XML or text declaration not at start of entity

Answer 2

Try this:

Add this to your config.php file:

define( 'CONCATENATE_SCRIPTS', false );

above the line /* That's all, stop editing! Happy blogging. */

Answer 3

"Particularly at the top and the bottom of your file... If you have some line breaks, your xml got an error : XML or text declaration not at start of entity"

In addition, you should remove intermediate occurrences of php's closing tag ?>.

For example:

    <?php

  ...code...

    ?> 


 ...Some HTML Code...    

<?php

...code...
