Worked for a while

So I have started optimizing images, worked nice as expected including webp, image quality,… 20 out of 10 stars. Until I reached about 50-60% where spinner indicating the optimization in progress for every image just stuck, nothing happening, after few minutes images just gone to unknown error, tried to contact support over the online chat, over facebook, no reaction. Also note that this will optimize your PDF file too, so if you have 10 images on the website but 200 PDF files, well it will burn your credits, so I had to hack the code to throw error if it tries to optimize PDF file.
