JSON Error after upload image

[linkref]

Hi, 

When I upload an image to a product, i get this error message using chrome.

Unexpected token s in JSON at position 2

 

But using safari i get this one :

JSON Parse error: Unexpected identifier "smushing"

 

I can code, but i don't know where to look...

 

Thanks you for your help..

I've got almost the same problem ! 

Unexpected token < in JSON at position 0

Anyone ?

This is basic debugging in Chrome (in other browsers it works quite similar).

Press F12. It will open the DevTools in the lower part of your window.

Assuming that this is an Ajax error you go to the network tab. When you then upload a file you will see the network operations as urls on rights side. See the image:

Now click the url of the image. You will see then a submenu where you should select Response. See the image:

When something has gone wrong you will find here an error message. That is what usually results in a JSON or other response error.

Here's the issue...

The Ajax call returns an error, the error is written as HTML.

Therefore the first (or other) character is "<" which is not JSON.

In my case, it was an out of memory error.

 

Hope this is more helpful to you.
