That’s exactly what I did, thanks, yes an option would be more than enough ??

That’s weird, just had a check to see it’s the latest version v1.1

By the way, what’s the difference between “HTML Rewrite” and “Server Side”?

Could there be a similar issue with “Server Side”?

Thanks, so i know i’m on the track

nobody knows?

by letting the request post to index.php, the problem is gone, ??

no use, i let ajax request post to functions.php, then all wp func in it return “Call to undefined function”

yes it is a separate file, i think i can try to include it to functions.php

very useful information, thanks

Dammit, how stupid i was! Thanks make it clear

It looks make sense and worth a try, thanks for the great knowledge share
