Problema com upload no Editor TinyMCE

Olá galera do mal,brincadeiras aparte.Vamos ao problema,sou novato no mundo do PHP.

Estou construindo um site com administração própria com seções... no Wampserver o Tiny_MCE não constou nenhum erro para fazer upload de imagens e tals,Mas quando hospedei meu projeto na Hostgator deu merda,quando clico na aba upload ele me retorna a página 404 do site.

Verifiquei as permissões das pastas e tá no seguinte: uploads ficou com 0755 e sua "pastas filhas"

pra simplificar vou por uma parte do código ai!

Esse código é referente do arquivo config_tinybrowser.php
