Hi everyone,

I would like to customize it so that the Administrator Email is hidden when accessing index.php, as in the LimeSurvey hostin.
If you have any knowledge, could you please help?

You can customize the index page via the survey theme editor. The page design is taken from the standard theme that is set in your installation. I know it is weird that the index page is part of the survey theme and not of the admin theme, but that's the way how it is.

You will need to "extend" the theme you are using to create a custom theme (if you don't have a custom theme yet).

Then go to the theme editor of this theme and choose the view "survey list", which is basically the index view.

On line 173 you will find something like that:
That is probably where you need to start to make your changes, e.g. delet this line or comment it out. I did the later and it worked just fine in the preview.
