TOPIC: [SOLVED] DT Register not woring - error message

Hi, My client is receiving this error when trying to access DT register on my site:

Fatal error: Cannot access protected property DtregisterModelCategory::$table in /home/floorcov/public_html/components/com_dtregister/views/event/tmpl/list.php on line 16

Please advise what I need to do to resolve this issue.

Site is floorcoveringsinternational-registration.com/register

DT Register vs 3.1.7.c
Joomla vs 3.8.3

As stated in your ticket (double posting support is not necessary)...

The issue is simple. You are using a version of DT Register that is almost two years old and expecting it to be okay with the very latest build of Joomla. You have to update DT Register. Your license is expired so you'll need to purchase a new license, which will give you another year of access to updates and support.
