Not working on Nginx

Can you please Debug on and see if there any error?
Other wordpress pages working correctly?
Is there any caching plugin or any other caching mechanism active? Is Nginx static caching enabled?
Did you set “Front End PM Page” in Dashboard > Front End PM > Settings > General?

Debugging don’t show errors. Another front end plugin (WP User Frontend) has same problem. Rest API didn’t work when I aks to frond end edit or delete post. I have category ajax in sidebar and it works, no problem.

I use Cloudflare but when I stopped it in Development Mode when “Temporarily bypass our cache allowing you to see changes to your origin server in realtime” or use only for DNS, no effect. Test with No Query String & Ignore Query String Caching Level and Respect existing Headers of Browser Cache Expiration, there is no effect.

Settings of Front End PM Page Dashboard are saved again, no changes.

I don’t know if Nginx static caching is enabled.

I don’t use another cache plugin or mechanism.

Any thing restrict frond end function. I disables all plugins and change to default WP theme. Test with only your plugin – don’t work. On localhost there is no problem.

Nginx have not .htaccess file. If test with some code directly to wp config file, just give me.

How you set up your Nginx? Is it a reverse-proxy in front of Apache or standalone?
What is wordpress permalinks structure?
Can you please disable all type of caching and cdn for testing?
Can you give me a access to your website?

Thanks a lot @shamim51
It turned out that the server is not configured properly for WP, and some small configuration is needed. To change WP permalinks to other, your server need: `location / {
try_files $uri $uri/ /index.php?$args;
}`
Thank you solving this issue!
