Get message
Call to undefined method Joomla\CMS\Application\AdministratorApplication::isAdmin() when change order status to 'shipped' and notify purchaser.
Error only appears when notify purchaser not on change of order status.

Hi,

This error probably comes from an old version of a plugin which hasn't been updated on your website.
Please turn on the "debug" setting of the Joomla configuration and reproduce the error.
You should get a more complete error message which will point at the location of the problem.

Hi Nicolas, I included the whole of the Joomla debug with my initial message. Did it not come through to you?

Hi,

The text "Call to undefined method Joomla\CMS\Application\AdministratorApplication::isAdmin()" is not the whole error message.
It's just the abbreviated message Joomla provides when the "debug" setting of the Joomla configuration is turned off.
Normally, when such an error happens, Joomla provides a more complete message, along with a call stack. Something like this:

Or like this:

We need the complete error message because the abbreviated error message you provided doesn't give any indication on where the problem is.
If you're unsure on how to get the full error message, please provide a super admin backend access via our contact form and we can look into it:

Hi Nicolas, I'd also included the full error message from Joomla in that initial post. Maybe it is getting stripped out because it was a table straight from Joomla? Here it is again, this time as text. Best, Terry

Hi,

Not sure what happened but the call stack was / is missing from your first message on my end.
Anyways, thanks, that's exactly what we need.
The callstack indicates that the issue comes from the file /media/com_hikashop/mail/order_status_notification.preload.modified.php
This file is an override of the preload section of the "order status notification" email. It is generated by HikaShop when you apply modifications to the preload of the email via the menu System>Emails. That way, when you update HikaShop, your modifications are not lost. The drawback is that you don't get the modifications we apply to the preload, like a modification to make the preload compatible with Joomla 5 which you must be missing.
So, I would recommend renaming that file via FTP, in order to deactivate that override.
Then, you can reapply your modifications to the preload of the email.

Hello,
Many thanks for your prompt reply. Renamed the file and on test I get no email notifications to purchaser.
Also I'm a little puzzled. As far as I know there are no modifications to the preload of the email from this end. Everything is as much as possible plain vanilla Joomla. The site only has Akeeba Backup and Admin tools, Hikashop and AcyMailing as extras - all are up to date.

Please ignore last message. Test email notification came through. Thank you for your support.
