Alright! I finally got around to trying that out.
I added dd($mail->ErrorInfo); for it to read:
dd($mail->ErrorInfo)
$CI->session->set_flashdata(‘alert_error’, $mail->ErrorInfo);
I did however run this script first and has no idea where to find the source files or how to use that tool. Remember, I run my 1.5.11 version on MAMP with the source files locally. Very simple setup. I just access InvoicePlane via localhost:8888/invoices
git clone GitHub - InvoicePlane/InvoicePlane: A self-hosted open source application for managing your invoices, clients and payments. ivplv1
cd ivplv1
composer install
yarn install && yarn grunt
Plus I ran:
Composer update
Aight, back to the error message from adding dd($mail->ErrorInfo):
An uncaught Exception was encountered
Type: Error

Does that tell you anything?
