2 weeks ago I tried to upload media to a new post. I got an error message saying "Error uploading image. Try again later". The image still uploads even though this error comes up however the file displays a blank thumbnail as an "unattached" file. If I try to attach the file to a post, nothing happens. At this point, I am not able to access media files from a post or upload any images regardless of the size. I have been searching for a fix and nothing has worked.
I have tried deactivating plug ins and re activating them one by one. I have changed folder permissions (755 to 777). So far nothing has seemed to help. Can anyone help me with this?
