hi,

I have a simple website with built in wpbakery on the theme. I am not expert on this, but there has not been any problem feew weeks ago. and later this day when i check it again, i can't see all the image that i published in my page. I already tried :
1. Re install theme : not solved
2. change to another theme : only few header are appear, the other are not
3. change php version : not solved
4. flush cache on browser and wp : not solved

the image always appear on back end and front end editor. but when it comes to published page, only the text and button are appeared, the image not showing at all. See my attachment.
Thank you
