If you are facing this issue please read following may help you to fix.

#1. Exclude current post/page id

If you are displaying post grid on a page or post also included on the post grid query it will create an infinite loop which may cause 500 error on your site. please go to post grid post query settings and add the post or page id(where you are displaying post grid) under the option “Exclude by post ID”
