In my wordpress, I tried to upload my images by media uploader but it says "couldn't create directory wp-content/uploads/2016/09". Then I create the folders correctly. And now when I tried to upload my files by media uploader, it says "couldn't move to directory wp-content/uploads/2016/09". Finally I uploaded my images in the folder and then checked the media library and the media library saying "no media founds".
Why is it happening?
