The uploaded file Could not be Moved to / home / public_html / wp-content / uploads /
When? - Error occurs uploadThe file via wordpress / dashboards / Write post.
Why? - Because the blog was moved (files + database) From one server to another and have lost attributes / permissions folders (chmod). (This is a particular case. Reasons may be others)
safe_mode_gid= ON (in php.ini)
chmod 777 wp-content /Uploads (via SSH or fTP)
