I guess there was something wrong with the returned json data. it could be some special characters or something else.

 

It seems that you have turned on the DEV mode, can you try to turn of the DEV to see if it works?

It might be some output of debug info break the code/data.

 

set _PS_MODE_DEV_ to false in file /configure/defines.inc.php

By the way, _PS_MODE_DEV_  should be off usually, you can turn it on only when you need to see errors for debug purpose.
