Problem with wp fastest cache and manual installation in the theme

Hello,

Thanks again for this great plugin. In the help function of the plugin a function is described to determine the position of the voting:

So that the plugin is not displayed twice, the placement must be set to X digits for all variants. If I use this code snippet it seems to work correctly.

The user is shown in the browser that he has now 1 voting. But in the database[wp_postmeta] ( _kksr_casts, _kksr_ips, _kksr_avg, _kksr_ratings) is “not changed”.

When turning off the caching (WP Fastest Cache), the plugin worked, and all votes were counted up correctly.

If I use the original function of KK Star Rating to determine the position (buttom left/right) without installing the code, the plugin also works with caching.

What is the difference between the two installation types?
