Can′t upload images

What happens when you try? Have you tried deactivating all plugins and switching to the default theme?

Also, did you clean up the hack completely?

Why? What happens when you try to upload images?

This is the message that appears

Error Bejos-bol19-1.JPG
Unable to create directory wp-content/uploads/2013/06. Is its parent directory writable by the server?

Try changing the permissions on the wp-content directory to 766. If you still have problems, try 767, 775 or 777. Once your uploads are working, change the permissions on wp-content back to 755 again and check that everything still works OK.
