the slider and the front page boxes do not appear when I configure the homepage on a static page. However they are displayed if I confide the home page to see the latest articles. I was using before the free version of Agama and I had no problem.
If you have a Static Front Page and you lost your front page boxes, open the Customizing ▸ Frontpage Boxes->General menu
and set Visibility on Front Page. https://prnt.sc/h8n9of
If your Slider disappeared too, please, edit your front page, (Dashboard->Pages->your front page/edit)
then scroll down to the bottom of the page, and enable slider on the page in “Agama options” meta box.
