fyi – I have backed out the 5.6.6. update now and the 5.5.9 version does not have the issue.
Any help appreciated

Short Update – I had a similar issue since with one of the sites product tag pages (a bit easier to find now). After re-creating the tag from scratch (and testing all the other tags on the site) all is now running well after 24 hrs.

For info: From the logs the flush happens after a call by ‘ao_speedup_cachebuster’ i.e.:
[Fri, 06 Aug 2021 12:00:30 +0000] [/wp/?ao_speedup_cachebuster=71254] [https://sitename/wp/?ao_speedup_cachebuster=71254] flush all
[Fri, 06 Aug 2021 12:00:31 +0000] [/product-tag/tagname] [-] storing cached page: true original true reason
[Fri, 06 Aug 2021 12:00:31 +0000] [sitename/] [-] flush all

My theory is that Autoptimize ran into some issue with caching this tag and this in turn triggered a flush event.

Hi Marco – just wanted to provide an update of my findings on this case.

1) I reverted the changes above – as that seemed to also cause inconsistencies when I try to manually purge the cache from the Admin console – so I reverted back to a normal installation which re-introduced the same behaviour.

2) I have identified the scenario that caused the ‘Flush All’ issue as follows:
2a) The issue only occurs when I have the YOAST SEO Plugin activated. With Yoast de-activated it does not occur.
2b) The issue also only occurs when I cache a specific page – in my case the contact-us page. Everytime this page gets cached – it triggers a ‘Flush All’ at the end and leaves all pages on the site uncashed (_old) again.

3. I tried updating the page (it was a very old one), changing the url (slug) and re-publishing, but the error persisted.

4. To correct the issue, I created a new contact page and swapped out the url.

I can’t figure out why this would only occur with Yoast activated as the ‘flush all’ normally only (normally) happens with a Yoast initial activation or de-activation.

Anyhow – Cache is looking normal – so far so good.

Per related post – What I have done to overcome this problem:

1.
/wp-content/plugins/w3-total-cache/PgCache_Flush.php
public function flush() {
if ( $this->debug_purge ) {
Util_Debug::log_purge( ‘pagecache’, ‘flush_all’ );
}
//comment out this line: $this->flush_all_operation_requested = true;`

2.
/wp-content/plugins/w3-total-cache/Cli.php
function pgcache_cleanup() {
$this->flush_all_operation_requested = true; // add this line

PS:

I suspect the performance culprit I had was the Automatic WordPress CRON that ran everytime Cloudflare visited the site. This is definitely also an issue if spammers try to attack you and wordpress runs its Cron at every visit.

Anyways – I followed the below steps to set-up the WordPress Cron Manually to run every hour:

My Site is stable for a week now and I replicated this to 2 other sites as well.

Cool ?? I think the trick is updating your nameservers first (Step2) to bypass Cloudflare

If the site still works after 24 hrs, then it is safe to deactivate Cloudflare (If Not – you can change the nameservers again)

Help please – I have the same issue – and renamed my plugin directory to get into the Admin console.

Issue now is I cannot update the plugin from the Admin Console (since if I activate it – I can’t get in)

Anyway to get the missing file to me please? or Some guidance on the steps to follow to get the update…

Thanks,
Pierre

Hi Stef

Apologies – I tried again on a non-cached site and this code worked for me:
.storefront-product-pagination {
display: block !important;
}

I just didn’t expect to look for it at the very bottom (after related Products)

I spent weeks looking for this solution and I am sure many more will appreciate the posted replies.

Thanks again for helping,
Pierre

Thanks Both

I tried the CSS from Stef, but no luck. The enhancement request also looks as if the GitHub request might have been cancelled?

The previous Product Pagination plugin seemed to have this feature, but is no longer supported.

Any suggestions on an alternative supported mechanism for a previous/next link on the Product page – or perhaps a premium add-on in for Woocommerce?

Many thanks,
Pierre

Argh – oh dear. Looks like there were changes made to the theme and the plugin was removed from the widget area. I will check with the designers if we can add it back and if there is still a problem I will let you know.

Thanks for the fast response.

Hi – Any support on this please?

Thx

Thanks a Mil – that worked ??
