Edit History

I have prestashop site where the category image updated in backend is not reflecting in front end. In BO image change is reflecting properly but in FO a previous image is always loading. It seemed like a cache issue at first therefore I cleare performance cache, tried removing cache in var folder, disabled caching on cloudflare etc but wasn't fruitful. On further analysis I found a module - superspeed by PrestaHero and it is likely that the issue isn't an issue but has something to do with module. The image loaded on category page is actually a webp image and which itself is from a setting in this module, I think. I do not have permission to disable the module and if anyone familiar on this module can share any insights on how to fix this would be very helpful. Hope someone has a solve. 

PS : renaming the module caused the site to be on error so that's not a possibility either.
