While working with WordPress, I came across this error:
The uploaded file could not be moved to wp-content/uploads/2015/06 .
After looking for several minutes, I found no answer. Then what I did to fix my issue is this:
I went to my FTP and changed the file permissions of my wp-content from 755 to 777.
This change allowed me to upload pictures from my IOS app and from the web.
Then when done, i went and changed it back to 755 for security reasons.
hope this helps.
