Working in develepor mode afther delete image cache in backend, the only images witch catch are getting refesch in the ../product/catalog/cache dir are on the frontpage of my Magento webiste. Product on catalog page's no image cache are refresd ans old cache url exist and points to a file witch does not exist any more. My only solution is to save every product by hand, then image and cache url are regenerated, but i have to do this manualy for 100 products. I try to save in bulk but that did not work. Any one have a solution?
I found a workarround, because de image ( widget ) on the homepage did regenrate cache and cache url. I made a widget for all product on homepage. Afther fist load a delete widget and all image are working again.
Not the best solution but workable for now.
Anyone with a better solutions ?
I'm having exactly the same problem on Magento CE 2.1.6, but unfortunatelly haven't found a better solution than yours. Adding a temporary widget does regenerate the image cache, but I agree this should be fixed. I hope developers a checking this forum from time to time, or should be better submit tickets on github...
Well, any bettter solution still welcome
