[Duvida] Include_once Erro

[EduardoLima2015]

Pessoal estou com problemas com include_once

Eu desenvolvi um sistema em php no meu pc sem problemas e quando eu subi para o servidor apareceu estas mensagens, alguém poderia me ajudar.

Olá!

Verifique onde está o arquivo conexao.php, se está na mesma pasta ou se o caminho está correto.
