No images available bug

Jul 18, 2014
So i am experiencing a problem whiched occurred a few hours ago, I opened gallery and it says there "No images available". I went to the File Explorer and there was (0) in images. I thought the system (or possibly clean master app) wiped out evert data I had, but I entered a few folders in the File Explorer and found out the images are still there. I find this to be annoying, I can't upload my pics to social media and stuff, I tried rebooting the phone but still, no changes. Any solution to this problem
