Don't display category/subcategory image in category description

[kenkomuri]

Hi folks,

 

I have a issue with prestashop 1.6.1.1 since my upgrade from 1.5. The images of the categories are displayed in the category/subcategory page and used as background. This causes the description can not be shown as the font is white also the background. I tried to delete the image category/subcategory but when I go to the parent category the image is not displayed.

 

My goal is to show the description in the category/subcategory without deleting the small subcategories thumbnails.

 

Thank you
