The code for displaying and generating “googlenewsfeed” on the page “Google News Feed” with selected “Page template” here:
https://pastebin.com/7ahHDmLN

The code for google-news-sitemap.xsl is here:
https://pastebin.com/urm7qFUN

That new “Google News RSS Feed” for Google News Publisher is called from functions.php with:

// register new Google News Feed RSS - because of the error of needed "full" description for post and content in body for guidelines
add_action('init', 'customRSS');
function customRSS(){
    add_feed('googlenewsfeed', 'customRSSFunc');
}
function customRSSFunc(){
    get_template_part('rss', 'googlenewsfeed');
}

The code for “rss.php” file which is displaying and generating “goolenewsfeed” RSS Feed here:
https://pastebin.com/8nm2MWLw

Maybe I have to change the code, or add the “page” or that “feed” under the “do not cache” somewhere?

Why that occurs on PHP 7.4 is more questioning, because it was working fine on PHP 7.2 until 5 days and it is still working on other Website running for 2-3 months on PHP 7.3.

The setup of the W3TC configuration (cache, redis, page cache, php, opcache, nginx …) and general Linux and LEMP web server is exactly the same.

Which PHP version are you running?

Same error.

Running latest version of this plugin with latest WordPress on Nginx and PHP-fpm 7.4

Thank you for reaching out!

That is true.
Me too, have not found any issues or topics regarding that.

I have to admit I have not yet tested the W3TC with the “APO enalbed” in the CloudFlare Dashboard.

Will try it out in the CloudFlare dashboard “enabled” and see what it happens with the tutorial written on CloudFlare website.

Will write back if I find out any issues in that combination, if so.

Nevertheless, thanks for great caching plugin!

Maybe the “cache invalidation” or “bypass” by Cookie? – not needed for now, but, hm .. maybe would be usefull for WooCommerce, if so?

Dear @vmarko

Thank you for fast response and helpful feedforward information regarding my questions!

Will do, as soon as possible.

Thank you in advance

Sincerely

And, I wonder is the current version already compatible with PHP 7.4?
Can I test it on my server environment?

Thanks

Thank you very much for provided information and help!

I hope I will get it working.

Basically if I understand it …
From that, I can setup/configure on my dedicated server and use different ports for Memcached – for each of those 3 WordPress Websites.

While also using, different Redis Databse ID – as I understand “max 15/16 databases per Redis instace” on the same port.

Great!!
Thank you for help and a bit of explanation!

In short, is it possible to use W3TC plugin with the:
a) multiple WordPress websites that have:
1. separated /home/www/domain-name/ folders
2. installed in different databases
2.1. different database names as well
2.2. different table prefix as well

b) while using a setup for each like:
1. Memcached – database cache
2. Redis – object cache

NOTE: 1. and 2. – running on the same instance?!

3. Page Cache – disk enhanced
4. CloudFlare extension built inside W3TC
5. AMP cache extension built inside W3TC

Thank you very much!

That would be great feature for this plugin to have a sitemap.xml for Google News also generated.

Ok, after restart nginx and php several times a day, it worked.

But still, it does not shows up the “successfull” notice everytime if cleared.
Moreover, sometimes either trows “unsuccessfull”.

I do not know.
Haven’t seen that before, 2 days ago was normally regarding the stated PHP 7.2 update.

All other, cache and stuff are working normally.

No problem.

Nothing to be worried about, now I found out that it only does not print out the notice “OPCache flushed successfully” or as it says already.

Do not know the reason, because it was showing the notice normally until 1-2 days ago before I have updated PHP 7.2 because of that vulnerability regarding PHP-FPM as stated on the attached link (start of the topic).

But it flushes the cache. I can confirm, I checked, the new code is applied after OPCache flush.

But, just do not know why it stopped showing notice about successfull or unsuccessfull flush of OPCache.

Strange behaviour, maybe due to something else.
Maybe it’s not realated to the plugin itself.

If I have multiple installed PHP version, like 5.6, 7.0, 7.1, 7.2 and 7.3

WordPress uses and runs on a processes of PHP 7.2.

Does the “Clear OPCache” tirggers 7.2 or? Maybe 5.6? Or all of them at once?

The “php-v” in SSH shows default version 7.3.

Should I set the default to 7.2, and then try to flush OPcache?

OPCache module is installed for all PHP versions.

Well, from my experiences, you shouldn’t use page cache while having Web pages like webshop, etc.

Because, yes, exactly that happens either if you use for example nginx fastcgi cache.

It re-writes your cached file always.

So, try the workaround, to bypass or with CloudFlare bypass by cookie installing Railgun.

Or, re-write your PHP code to check if cookie A or cookie B, display the corrent menu?

What are CHMOD privilegies and is there the right owner of the directory cache, and sub-directories?

Are you using W3TC and some CDN like CloudFlare?

What web server you use? Apache or Nginx, or some other?

Have you setup the .htaccess or .conf (nginx) correctly for redirection and using the cached index.html files?

When you purge page file cache, you should see _old suffix and index.html as new one generated.

Maybe you have to visit your URL again, or the same page in other browser, so the server would be triggered to make the cache of it and later on serve new cached index.html to the further visitors to that URL.
