No Email to Customer or Store Admin

Mijoshop 2.4.4
OpenCart 1.5.51

I have set up (since PHP Mail doesn't work) SMTP in the Mail settings but neither the customer nor the Store Admin receives emails after an order has been made. The only time an email gets sent is when the Store Owner modifies the History of the order, which isn't right.

I would like a confirmation email sent out to the customer after they've made their order and the Store Owner to receive an email after the order is made (which the radio button setting for this option is set to 'Yes'). This would make sense wouldn't it?

So where do I begin debugging? Error Logs show nothing in regards to these problems.

#2 Problem:
I'm using a sandbbox account to test orders and the orders are NOT showing up in the Orders tab. Any way to figure out why? This is obviously not normal.

I've tried to go to Mijoshop forum, but I keep getting a white page telling me that I do have access to the website (not sure what that means since I'm a member). Therefore, I've had to come here for assistance.

Thank you to anyone who can help me figure this out.

any updates on this?

My settings were made like this:

Mijoshop:
Mail Protocol: Mail
Mail Parameters: whoever is to receive the email
New Order Alert Mail: Yes

Joomla System Global Configuration:
Mail Settings:
Send Mail: Yes
Mailer: SMTP
From email: create an email on your web host that can be used for an admin email and enter it in here
SMTP Security: none
SMTP Port: 25
SMTP Username: email addressed used in 'from email'
SMTP Password: enter password here
SMTP Host: localhost

Things were working after that.

I don't think that I am using Mijoshop.
I believe it's all PHP.

Mijoshop/OpenCart doesn't matter. Mijoshop is OpenCart (1.5.5.1) just integrated for Joomla.

ok, Thanks! How do I get to the Joomla global settings as noted above?

System > Global Configuration menu

I don't have that option. Under system, I only have setting, design, users, localization, error logs, and backup restore.

What version of Joomla do you have?

Honestly, not sure. I walked into this project. The site I believe hasn't been altered for over 2 years. I have never worked with open cart before now. So, please excuse my ignorance on the subject.
Is there a way for me to upload a screenshot to this forum without waiting for admin approval?

You're welcome to email me.
