I am a subscriber, I know!
I want to thank Shabti for his excellent help resolving this issue. I am using 2.8.8 for now. There is no SDK conflict in this version of free ACF frontend.This issue was caused by a SDK and has nothing to do with ACF frontend.
The ACF frontend is a major piece of software for any serious frontend developer who wants to use both the wordpress core post functions ,and custom posts on their site.
It is a major contribution to wordpress post development.
