Front page setting not working on bitnami

I’m setting a demo of my site using Bitnami and the Perth theme.
I followed all the instructions to set a custom Front Page. But after choosing the relevant page on the dropdown menu in the section “Static Front Page” and hitting the “Save and publish” button, the home page returns automatically to the article-type layout.

The “Posts page”, instead, is clearly recognized by the system and marked so also in the pages list on the dashboard.

Since I’m not actually on-line but just working on local mode, may this be a problem caused by the use of Bitnami?

Thanks a lot.

Hello there,

I am sorry to hear that you’ve run into trouble.

Does this issue also to happen even with the default WordPress theme? Please confirm.
