I’m using w3tc_flush_post function to purge the page that has a shortcode. A shortcode has a value changed. The change is determined by clicking an Update on the admin site. A plugin.

This works before but not now. Even using Purge current page does not work.

Hi Marko,

The plugin is working before the previous release. As for the current release, when I click “Purge current page” it does not work. The old value in the page which was already change does not reflect.

In the page source it says:

Object Caching 0/0 objects using memcached. The same when using Disk as cache method.

I have the same problem.

@wfphil,

If I remembered well, it happens after I update/upgrade Ubuntu 18.04. Update includes but not limited to MySQL and PHP.

Hi @wfphil,

Sad to say but the error is back. And it gives a lot of CPU load on my server with this Deadlock error. After uninstalling it manually, the load of my server were back to normal.

I can confirm that the workaround above by wfphil is working. Deadlock error is gone.

Hi @wfphil,

This seems to be working now. No deadlock error yet for several minutes.

I’ll update here again if I encounter the same problem.

Thank you for the support.

Hi @wfphil,

It’s been 2 weeks and 4 days since I send the diagnostic report. Any update on it?

Hi,

Just send the email under the Diagnostics tab.

Thank you

Hi,

I have already done all the suggestion and the problem is still there.

Hi,

Yes, the shortcode is on a page. When we change the value of the shortcode and after clicking the update button, it fires this code: w3tc_flush_post($post_id);

But it’s not working. BTW, what’s the action/filter to fire a callback when the update button is clicked?

Hi Marko,

I put the code in my plugin behind the update button. When the update button is clicked, the following code will be called:

if (isset($_POST['edit_result']))
{
    ...
			
	if (function_exists('w3tc_flush_post')){
		w3tc_flush_post($post_id);
	}
	
    /*if ( function_exists( 'w3tc_pgcache_flush' ) ) { 
        w3tc_pgcache_flush(); 
    }*/
	
	...

}

Thanks for the help.

Hi Marko,

Did you try it or double check if it’s working?

Hi Marko,

Did you test it on your end? If you can double check that it’s working, please do let me know. Because I’ve already tried it myself several times and it’s not really working.
