Error uploading image Since I changed my drupal to my backup that it's giving me some errors, but overall it stills working, but today I was about to add a new content and when I try to upload new images it shows me this error 


  "The file could not be uploaded."


And in log messages I've this message errors:


  Location: http://localhost/node/add/imovel?_wrapper_format=drupal_ajax&amp;ajax_form=1&amp;element_parents=field_image%2Fwidget
  
  Message: The upload directory public://2017-02 for the file field field_image
  could not be created or is not accessible. A newly uploaded file could
  not be saved in this directory as a consequence, and the upload was
  cancelled.


In the same location this 2 other errors:


  Recoverable fatal error: Argument 1 passed to Drupal\Core\Form\FormState::setError() must be of the type array, null given
  
  Notice: Undefined index: value in Drupal\Core\Field\Plugin\Field\FieldWidget\NumberWidget->errorElement()


Now I can't upload images and that don't allow me to add new content.
I already try to create a new field but that didn't work.

PS: I think the error has to do something about Image Crop because before this error happen a box to crop my image would appear after I upload and know I upload and no box to crop the image.. And when I press save and publish content the error pops


  The specified file temporary://filekrGdEp could not be moved/copied because the destination directory is not properly configured. This may be caused by a problem with file or directory permissions.
This sounds very much like a permission issue. Please check the permissions of 


  /home/user/public_html/sites/default/files/2017-02


The directory must be writeable for Drupal. Set its permissions at least to 710. You might want to set them for testing purposes to 755 or even 777 to see if your error messages disappear.
