Por causa desses confrontos a página fica assim:

/applications/core/interface/imageproxy/imageproxy.php?img=https://uploaddeimagens.com.br/images/000/642/807/full/Sem_t%25C3%25ADtulo.png?1466113229&key=373ca4d1671c48fd87c26aea4275777e35d2049e68beb8da397d4afcfc5ead1c" alt="Sem_t%C3%ADtulo.png?1466113229" />

Deveria ficar assim:

/applications/core/interface/imageproxy/imageproxy.php?img=https://uploaddeimagens.com.br/images/000/642/809/full/g.png?1466113316&key=384615deff78c9e6063ec51cb1d671e094a9974ad3678fd89c40c074243a5825" alt="g.png?1466113316" />

Gostaria de um passo a passo de onde se encontra esses links para realizar a troca do http para https e assim o redirecionamento ficar completo, da seguinte forma "wp-content>theme>etc"

Hospedagem: One.com
Plataforma: Wordpress
Template: Creta (http://wordpress.mag...emes.com/creta/)
Site: sacchettoboutique.com

Bom, espero ter sido bem claro no meu post, e não ter deixado dúvidas para solução da questão.

Fico aguardando um retorno! ;)
