Image thumbnail styles are not created I'm moving a website in a production server and it appears that the image thumbnails aren't created from an Image Field in a content. 

The images are uploaded correctly but no files are created in styles folder. I've already set to 0777 each folder in case of a permission problem, but it's not that. 

The big problem is that I can't remove the images, probably because it raises a forbidden file as it doesn't exist. The only error log I can find is an access denied but nothing else.

Does anybody has the same problem ? 

It works okay on local... maybe an Apache issue to look at ?
Solution for Drupal 8 that worked for me: 


  create sites/default/files/styles folder manually
  set its permissions to 775
  create .htaccess file in this folder with following content:


&lt;Files *&gt;
  SetHandler none
&lt;/Files&gt;
