1 & 2, both point are solved. but I have one curious question. If they had a problem with cache & masonry layout how come everything becomes correct after login?
3. As of this point is considered, I resized images as told by getting metrix for better loading of the website.
4. For the above point what should be the dimensions of the images so that they show perfectly in 3 columns without t much gap on mobile & laptop. As of now they have 117*117 dimension
