can you show me the configuration?

I do not know in what form I have to show the configuration. Do you have to enter your login details? I would not like to do this in a public forum. In the meantime, I am sending the screen "invoice-conf.jpg".

I just realised something: your invoices are not created "automatically" (from another extension integration), you create them manually.

This means there cannot be "automatic email", you actually need to "click the button", to send the invoice

that's the normal behavior.

I do not know what you mean by "you create them manually".
To create invoices (except Invoice Manager) I have only one plugin - https://dj-extensions.com/dj-classifieds/apps/invoices-app
There is no question of "manual" invoice creation. I certainly do not do it myself. I want everything to happen automatically.
However, the automatic creation of invoices is set and as I understand it is not related to sending them or not sending them.
See the screen "invoice-conf-plugin.jpg".

ah! ok you're using DJ classifieds.

then you have to ask them, as this is NOT a plugin that we have developed. If sending the invoice is not working means that there's something in this plugin not working.

I can't help you with that, as we're not the developers and mantainers of this specific plugin. You need to ask the DJ classifieds people.

The same is what the creators of "DJ Classifieds" wrote to me ...
And I think they are right. This is not a plugin "DJ-Classifieds - Invoice Manager" I have to send an invoice, in it there is no such option.
I only see the option to send invoices in the "Invoice Manager" component, so you should help me.
https://www.joomlathat.com/invoice-manager/e-mail-invoices - here you write about it.

hello

in the link you send me, it explains precisely what I was telling you: you need to hit the "send invoice" button manually to actually send the invoice.
that's the only option available in the component.

I'm very sorry to tell you that the DJclassifieds people maybe don't know what they're talking about.

if what you want is that, when a new invoice is generated through the DJ-plugin, this invoice is automatically sent by email, right away, then this is something that needs to be built IN THE PLUGIN, it's not in the component.

Trust me, I'm the developer of Invoice Manager.

Maybe the DJ developers didn't add that option in their plugin - which is a shame.

all our plugins (the ones WE developed and that we distribute, for example VirtueMart, HikaShop, etc) have the option to "automatically send the invoice" built in.

Do you understand what I'm saying?

Ok, thanks for the explanation.
I will show this conversation to people from DJ Classifieds.
