I am trying to create ACF for my custom theme that i have created and installed in WordPress already. this WordPress has 2 themes (one is the main theme that has 5 pages & another theme that has ACF linked to it as the front page) multi theme plugin is use for the second theme to work. now i have another theme (third theme) that I want to create ACF for it and I will use the multi theme plug in as well. the problem that when I change the reading setting of the second (theme) page all content disappears.
how can I add ACF to mulcible themes that installed in one WordPress
