Page caching seems not working for both dynamic and static pages.

Hi mate,
looking at the response header of your webpage it doesn’t seem like the plugin is installed in your site. Can you please confirm?

If the plugin was installed then there are supposed to be a few extra response headers there added by the plugin.

Hi Saumya,

Yes it’s installed, active and even the page cache is enabled.

Hi,
looking at your list of plugin I do not see any other caching plugin involved. Can you check with your host if they have some sort of page cache enabled at the server level which might be removing all the custom response headers, setting the cache-control to max-age=0 and not letting the plugin to manipulate the cache control as it needed.

As far as I can see I think this is happening with your hosting issue. I think your hosting company has some sort or page caching enabled at the server level. can you please check with them and confirm that? If they have some sort of page caching enabled at the server level, that needs to be disabled on your site.

Ok sure, let me talk to them.

What exactly should i ask them?

as I said ask them if they have any server-level page caching enabled

they said they disabled it, yet the same error. can u check plz

Hi,
sorry for the delayed reply due to the weekend, from what I can see is you have installed the default Cloudflare plugin on your site along with enabling APO: https://i.imgur.com/ZgGGJjZ.png

Can you please confirm it? I am still not seeing the response headers that are supposed to be added by this plugin.

If you have installed the official cloudflare plugin, please make sure you disable and remove that along with disabling APO inside your Cloudflare dashboard.

You cannot use this plugin as well as the official Cloudflare plugin. You need to choose between one.

i was checking other plugins if the issue presists,
its deactivated now, only your plugin is activated
please help

Hi,
I think you have tinkered around the plugin settings and made some mistakes along the way. Try deactivating and uninstalling this plugin and install it as fresh. Then provide your CF API details and enable page cache. After that let me know.

APO is off , as it’s a free plan

Deactivated, Uninstalled, Installed Again, Activated again with the API, YET the problem remains lol

Hi,
alright now as I can see that the plugin has been installed properly. So, there is no issue on plugin’s end.

The reason you are facing this problem is because for your first request i.e. one with content type text/html your cache-control header value is forcibly set to no-store, no-cache, must-revalidate. Screenshot: https://i.imgur.com/6cAiym9.png

Which is basically telling Cloudflare to bypass cache on that page. Now look at your list of plugins and check if you have any other caching related plugin installed which might be adding this cache control header.

If not, check your must-use plugins section and if there is anything that might be doing it.

If not then this cache control rule might be getting added by your host. In tact case you need to contact your host and ask them to remove this cache control header that they are adding so that the plugin can add it’s own cache control header.

If you also have a .htaccess file in your hosting environment, check that as well, maybe there are some rules there that might be adding it.

To summarize, now the plugin is installed properly but something is modifying and overwriting the cache control heqader value of your response before the plugin can do it’s work. So, you need to find out what is adding that cache-control rule and remove that.

Hi
In the MU-Plugins folder, the only file is
endurance-page-cache.php.bak

should i delete it?

yah you can delete it. But that is not adding that cache control header as that file is basically a dormant file as someone changed the file extension from .php to .php.bak so that the file doesn’t get executed. You need to find what is adding that cache control header. Don’t forget to look inside your .htacess file as well if you have that.

soo i saw the htaccess and theres alot of cache control stuff going on there
what and which one to remove?
