Hi,
I don’t exactly know how it happens, but every time someone visits a page with the Instagram widget on there, the images are stored in the media library. So when I checked, there were more than 2000 images from Instagram (the same images) stored. This takes up a lot of space and also slows down the website massively.
It could have something to do in combination with Optimole optimizing all the images, but if so, please let me know. Because I excluded the classes of the image containing divs already, but the images themselves don’t have a class, so maybe they still aren’t excluded.
