Faveo-helpdesk not currently compatible with PHP7.3 - needs PHP7.2

[JedMeister]

Alfredo reported in the forums that it appears that Faveo-helpdesk is not compatible with PHP 7.3. 😢

As per my response(s) over there, I have confirmed that there is an issue with PHP 7.3 and that it works ok with PHP 7.2. The main issue we hit was ladybirdweb/faveo-helpdesk#1293.

We will release an updated appliance (v16.1) with PHP7.2, but it's far from ideal as PHP7.2 is EOL.

The workaround for TurnKey users who have v16.0 installed is to downgrade PHP to 7.2. The easiest way is via the script I wrote:

wget https://raw.githubusercontent.com/JedMeister/downgrade-php/master/downgrade-php
chmod +x downgrade-php
./downgrade-php
