background image is not repeated but enlarged

Hello,

I have an issue with the configuration when setting a background image. I select “repeated pattern” (in French configuration : “Motif répété”), but instead of repeating the pattern, the image is enlarged to the screen width.

I have checked the css and it says “background-repeat: repeat;” in “body.custom-background”, so it’s supposed to be alright, but it’s not. I don’t have time to check any further. Could you have a look please ?

Thanks for your help !
