Hello!
Thank you very much for the great plugin – very good speed and quality of work. But there is one problem, the solution to which has not yet been found.
The “Only modified pages” option in the plugin settings does not work.
As I understand it, when the page is refreshed, its cache should now be immediately flushed and refreshed, but this does not happen. The page is still shown to site users without any changes I made (until the cache lifetime specified in the settings expires).
At the same time, the load on the server is generally practically zero. The problem occurs both on the hosting and on the local server, where there can be no load at all.
Do not tell me what it might be connected with.
Thank.
]]>If you upgrade the PHP version to PHP 7.2, PHP 7.3 or later, the “Hyper Cache Extended” plugin will show the following warning in your WordPress site:
Warning: Invalid argument supplied for foreach() in /.../wp-content/plugins/hyper-cache-extended/cache.php on line 392
This is because in PHP 7.2+ the foreach loop no longer supports iterating over null / missing / invalid collections. You need to add a check for null or invalid collection.
How to fix this issue?
The best way is to wait for the plugin author to fix the issue, but this did not happen yet. There is not PHP 7.2+ compatible version of the “Hyper Cache Extended” plugin.
Until an updated plugin is released, use the following fix, directly in the code. Just add a check in the code, using the WP plugin editor:
Change the lines 391-400 in the original code (causing the PHP warning):
$hyper_agent = strtolower($_SERVER['HTTP_USER_AGENT']);
foreach ($hyper_cache['mobile_agents'] as $hyper_a) {
if (strpos($hyper_agent, $hyper_a) !== false) {
if (strpos($hyper_agent, 'iphone') || strpos($hyper_agent, 'ipod')) {
return 'iphone';
} else {
return 'pda';
}
}
}
Use the following fixed code, compatible with PHP 7.2+:
$hyper_agent = strtolower($_SERVER['HTTP_USER_AGENT']);
$mobile_agents = $hyper_cache['mobile_agents'];
if (is_array($mobile_agents) || is_object($mobile_agents)) {
foreach ($mobile_agents as $hyper_a) {
if (strpos($hyper_agent, $hyper_a) !== false) {
if (strpos($hyper_agent, 'iphone') || strpos($hyper_agent, 'ipod')) {
return 'iphone';
} else {
return 'pda';
}
}
}
}
This is a screenshot to fix the Hyper Cache Extended plugin incompatibility with PHP 7.2+ directly in the WordPress plugin editor:

This is a pull request, holding the fix in the GitHub plugin mirror repository (plugins.svn.www.ads-software.com do not support pull requests): https://github.com/wp-plugins/hyper-cache-extended/pull/1
]]>The plugin works fine – been using it on my websites with no problems.
However, a client’s website, that uses Polylang for 2 languages has problems with this plugin.
Homepage – and homepage only – won’t allow more than one language change. More detail: you can go to the homepage in default language. You can click the alt. language icon to show the alt. language. BUT – if you switch back afterwards, it no longer wants to show home page in the alt. language – always going back to the default language.
All the other pages load with no problems and allow for countless changes of language – no problems.
]]>Hi,
Our in-house host is unfortunately on Windows / IIS / MySQL / PHP (WIMP), load balanced using F5 Big-IP. I originally tried Super Cache to speed things up but found it was not “cluster aware”. Would return different results depending on which server in cluster was it. Since then, my research showed that Memcached/Batcache (or Memcached Redux) or Wincache/W3 Total Cache were the only cluster aware object cache cobminations, at least as far as I could find.
I just read an article highly touting Hyper Cache for Windows / IIS, but couldn’t tell if it is cluster aware. Can you give me some guidance on this, or any related advice? We’re currently experiencing almost 3 seconds in TTFB (time to first byte), and I’d really like to reduce this to about 100-250ms!
Thanks!
]]>Whenever I update my Divi theme, the CSS breaks because Autoptimize’s CSS URL changes. I think it’s because Hyper Cache Extended is not clearing itself. I have to manually clear the HCE cache every time Divi’s theme (or Autoptimize) gets updated, and that is a big problem because Divi gets updated often and I have many sites.
To fix this problem, can you please hook into the upgrader_process_complete action and provide a new settings option to automatically clear the cache when the theme or plugins get updated?
Thanks for the help!

I’ve tested the original Hyper Cache-version on single WordPress sites and usually get better results than with the bigger Wp Supercache or W3 Total Cache.
But doesn’t run on multisites.
Thanks!

]]>What does Max server load average do?
Let’s say I set this to 2, does this means when the load is below 2, then this plugin doesn’t server the cached page? or does this means it will always serve the cached page, but will not recreate the cache when the load if above 2?
Thank you.

Is HCE working with Nginx? This: https://codex.www.ads-software.com/Nginx create an impression that only SuperCache and TotalCache can do it.

The result is that these new posts don’t show on the home page until cache expires.
please fix this issue.
Thanks
Hello, I noticed that plug don’t invalidate homepage cache when new content is pubblished. There are no option to enable this feature in this plugin.
i have published new post and it is not appearing on home page.
The only option for homepage is: DO NOT cache the home page so it is always fresh.

]]>Hello. I`m using WP with external php script, that puts posts directly into DB, using giving ID (posts parsed from another site, and id of this post represent unique id of the post, so i can see if i already parsed that post). How can i manually delete cache file for the home, archives, categories after creating each new record in database?
Ive try to use wp_update_post with giving id, but this function not updating, it creates new database record with new id.
Currently i`ve simply delete all hypercache cache files after puting new post in database, but it weir path, and i want to delete cache of only changed pages = home, archive, categories.
I see some errors after going to WP 4.
Just enable debug and see them.
Does that mean that it doesn’t work with WP 4 ?
thanks
]]>Will not save setting when I set Configuration > Cached pages timeout to 0 minutes (Minutes a cached page is valid and served to users. A zero value means a cached page is valid forever.)
As soon as I update after setting it to 0, it defaults back to 1440. Any ideas on how to set this property so that it stays? Somewhere in a SQL table perhaps?
My pages are almost never updated, so there is no need for them to be cleaned out. I will do that manually if I ever need.
Thanks!
