[SOLVED] Error 403 while uploading image in product

[Gianluca Bergomi]

Hi,
my e-commerce is online and working with almost 50 products properly configured.
Suddenly, this mornign, I can't upload images in my products. As you can see in the attached picture the respondig error is the following:

Quote

Forbidden
You don't have permission to access this resource.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

I don't understand what what could have happened since the code is all under GIT versioning and there are no changes.
When I try to upload an image prestashop make a call to https://mysite.com/prestashopfolder/backendfolder/index.php/sell/catalog/products/image/upload/78?_token=R7y74PwdAGgbO0cha4shBIkI6BrTJSqRICBfavtVnCQ and this call return 403.

I did not change anything in  the permission neither in the .htaccess file.

Thanks in advance

I noticed that there were only 2 products that were causing problems ... so I deleted them and recreated those products.
The situation appears to have returned to normal.
