Wordpress Cache-Enabler Plugin WP Cacher Enabler Plugin by KeyCDN folks

I typed it into my ssh console as root. Yes, I installed this via option 22 and followed your guide how to switch to keycdn cache enabler...

 

Hm, my post pages cached. May be I edited try_files:

Code (Text):

    location    /               {
        rewrite ^(/.*)/$        $1 permanent;
        access_log              /home/nginx/domains/domain.tld/log/access.log combined buffer=256k flush=60m;
        #try_files              /path_to_wp/wp-content/cache/cache-enabler/www.domain.tld/${request_uri}/index${webp_suffix}.html /index.php?$args;
        try_files               /path_to_wp/wp-content/cache/cache-enabler/www.domain.tld/${request_uri}/index.html /index.php?$args;
    }

I do not use the include and all pages cache.

 

Hi @eva2000 and all member who use Cache Enabler..
Had all of you realize something when update to latest Cache Enabler??
3 of my sites using Cache Enabler with Centmin 22 Option to not Cache Mobile Device..

After Cache Enabler plugin update 2 days ago, suddenly 3 of my sites can't see any update posts if browse using Mobile Device..I must manually Clear Cache if i want to see those updates by Mobile..
This is never happening when using Old Cache Enabler Plugin before update..

 

I'm getting error 500 while browsing on mobile. I had to disable Cache Enabler.

 

After did exactly you posted nothing is changed..
We can't see Post update in homepage when using Mobile browser (test with default browser and Chrome)..
So i must clear cache manually after update post for Mobile visitors..

 

Ohhh forgot to reply back about the issue in here, at that time problem still there even after update the plugin, also i don't use clearfy..
Even i restart the server, problem still there..
So i decide to change the cache methode, and problem is gone..

 

Hi

it seems like nginx does not send cached pages to my site.
missing status line <!-- Cache Enabler by KeyCDN @ .... (html gzip) -->

big TTFB (~1sec)
I am using cloudflare.

I also tried WP Super Cache. Same situation as with Cache Enabler, no status line, big ttfb.
Both plugins are working correctly on my localhost machine (apache2 + mod-php7.2)

Wordpress installed through menu 22 option + Cache Enabler. Site imported with duplicator.

what can I check?

 

Yes, I did tests in incognito mode.

file and group permissions are correct.

I replaced my domain with example.com

Code:

Static pages exist.
permissions are 755 nginx:nginx

I don't know how to share image here.

Lines I changed/added in standard config as I could remember

Code:

listen 443 ssl http2;
...
rewrite "^/([^/]+).html$" https://example.com/$1 permanent;
...
include /usr/local/nginx/conf/cloudflare.conf;

btw, why curl shows http/1.1?

 

I did a fresh WordPress install for testing purposes through centmin 22 option. Cache works.

I have no ideas.
Both WP Super Cache and Cache Enabler for main site do not work.
Cached pages are created but not served.
I made this assumption based on the long response of the server and missing status line.
But they works at the localhost.
