I installed a brand new template, everything is updated en still no background image is showing up. For now I placed the image in the container but that is not the best option. I have tried some css codes I found in previous topics, but that didn’t work out: http://www.twietcreativemarketing.nu/weesfietsen
Unfortunately, I am not certain about your issue based on the information you have given on your post. Can you clarify on which element you have added the background image that is not working?
