Image upload failures after server PHP update

[Bigin]

I think it could be a bug in PHP 5.6. The warning corrupting the json response in your uploader.php
The error means: you are sending an empty request. This error occurs when requests with empty parameter is passed.

Solution:
If you are using CGI you have set always_populate_raw_post_data = -1 in the php.ini
Or put the following lines in .htaccess file:

Code:

<IfModule mod_php5.c>
    php_flag always_populate_raw_post_data -1
</IfModule>

And keep php error reporting turned off, items manager and other plugin is still bugged as hell.
