front page won't change templates

Question

I have tried changing the template of the attached page and changing which page is attached as the home page, no effect for either. The front page remains the same. I am at my wits end with this one!!

Answer 1

What is your setup for front page in Settings > Reading ?

Do you have front-page.php template in your theme? It will pretty much override anything, no matter what you choose in settings.

Answer 2

ok, the question is from 9 years ago but the answer is still valid:

function custom_template () {
     return locate_template ('page_custom.php', false);
}
add_filter ('frontpage_template', 'custom_template');
