Found recent Pagespeed related error messages in the Apache error log:

We suggest disabling pagespeed and check if that improves the behavior. Please check the following guide to disable Pagespeed:

https://docs.bitnami.com/general/apps/wordpress/administration/use-pagespeed/#disable-pagespeed

Issue enabling Varnish

Describe your issue as much as you can

Trying to setup page caching for our servers. I'm using a live DEV server we use, before executing in UAT & Production.

Using this link - https://docs.bitnami.com/azure/apps/wordpress/configuration/configure-varnish/

I have come to the stage where I need to enable Varnish.
When I have come to this page - https://docs.bitnami.com/azure/apps/wordpress/administration/configure-use-varnish/#enable-varnishtm

I have disabled "PageSpeed" as recommended as part of the setting up of Varnish.

Then attempted to enable the service. I'm able to successfully execute the first terminal command line.
However, there is an issue when trying to execute the second terminal command line
"sudo mv /etc/monit/conf.d/varnish.conf.disabled /etc/monit/conf.d/varnish.conf"

As the directory "monit" doesn't exist.

I can confirm that "gonit" service is running on the server.

I'm unsure on how to proceed.

Hi @pjwilson1977,

Thanks for using Bitnami. I see in the bndiagnostic bundle you are using a previous image for the Bitnami WordPress solution on Azure. Can you give the most recent image a try? Our docs are supposed to work with the most recent version of our solutions.
