Hi everyone,

I'm having a bit of an issue with the PHP on my client's site. Up until recently, everything was working fine, both with the PHP email and online store.

Then, last month, a few things happened at the same time: I updated the program to the newest version (2023.1), and my client's webhosting updated their servers. With it came a litany of problems where nothing related to the store or the admin page was working. Customers were getting "generic error" messages in the cart, and my client would get "can't connect to the database" in the admin page. My client's customers couldn't put any orders through during this time.

I was trying a variety of things to fix it, and contacted the webhost with little success.

My webhost did show that the PHP version I had (7.2) was deprecated and suggested I update it. I updated it to version to 8.1, but there was no change. It would turn out that the culprit (at least on the admin page not working and the error messages) was because in the webhosting update, they changed the names of all the databases without notifying us about the change. I updated it in the parameter page on step 5, and orders are going through once again.

But now I'm faced with a new problem.

I know this is a lot of backstory, but since there were so many changes, I'm not sure what exactly is the culprit, so I'm explaining quite a bit just in case one of these details ends up being the solution.

My client is noting that, while orders are going through, and she is receiving the payment, she isn't receiving the email confirmation on her end from the site. I tested the system out and while I do receive the online products, my client doesn't get any email confirmation.

She gets the email from Paypal with the payment confirmation, and that's it. I have verified, and the box is checked off in the shopping cart settings to email her about the order.

I checked on here and saw some people reporting problems with 8.1, so I rolled it back to 8.0. While the store continues to work, my client still isn't receiving her emails. I also checked out the test page on the admin site, and while everything passes, the "test email settings" doesn't seem to be working - I have sent multiple emails to myself but it doesn't go through. The email log is also not showing anything, just a message from 2020.

I did see some people also report problems with 8.0, but the webhost has a message stating: PHP versions PHP 5.4, PHP 5.5, PHP 5.6, PHP 7.0, PHP 7.1, PHP 7.2, PHP 7.3, and PHP 7.4 are deprecated. We recommend that you update to a supported version of PHP. 

Since the only older version of PHP beyond 8.0 is 7.4, I tried it as well but there doesn't seem to be a difference either.

I'd appreciate any help.
