After downloading WordPress 3.5.2 files to our server, I uploaded said files to our host's server using Filezilla.
All the files were uploaded except the following Fail Transfers (with the reason being that "Could not start transfer":
/wp-admin/includes/class-wp-filesystem-ftpext.php - 2,920/11,140
/wp-admin/includes/plugin.php - 46,720/61,389
/wp-admin/plugin-editor.php - 0/11,067
/wp-admin/ms-edit.php - 0/210
/wp-context/plugsins/akismet/akismet.gif - 0/2,777
/wp-includes/post.php - 2,920/177,406
/wp-includes/update.php - 4,380/14,612
/wp-includes/js/plupload/plupload.flash.swf - 0/18,958
/wp-includes/js/swfupload/swfupload.swf - 0/12,767
/wp-includes/js/tinymce/wp-tinymce.js.gz - 0/115,794
The number to the left represents the amount of the file that was uploaded to the server. The number to the right represent the size of the file in bytes. As you can see, 4 of the files uploaded partially.
I later tried to individually upload each file to the server, with no success.
Any ideas anyone?
