Invoice PDF - A PHP Error was encountered

Hi All,

Been using InvoicePlane 1.4.3 since 2 years now. Just today when I was trying to download PDF of an unpaid invoice, I got this huge list of PHP Errors which I have never seen before. I have not made any recent changes to the settings or code of InvoicePlace.

Error Logs from /public_html/invoices/application/logs/log-2018-01-25.php

Browser Error Details:

Apache Version: 2.4.29
PHP Version: 5.4.45
MySQL Version: 10.1.24-MariaDB-cll-lve


First, please update to the latest stable version. 1.4.3 has several bugs and security issues.
