TOPIC: [SOLVED] the page with a list of events not displaying

I have updated my Joomla 3 website to the latest version and the page with a list of events is not displaying (blank page). www.luxreal.lu/events.html
Switched on debugging system shows:
Whoops \ Exception \ ErrorException (E_ERROR)
Cannot access protected property DtregisterModelCategory::$table

0 Whoops\Exception\ErrorException
/­home/­luxrealogb/­www/­components/­com_dtregister/­views/­event/­tmpl/­list.php16

$categoryTable = $this->getModel('category')->table;

Please, advice how to fix this. Thank you.

The fix is the same as noted in a number of other forum threads... you have old items in place still. DT Register had to update most of the view files due to a change in Joomla. Any template overrides that you have in place HAVE TO be updated. You need to get the new version of the file, re-apply any of your customizations, and load that into your template overrides directory. Old override files can't remain.

Also, make sure all DT Reg modules, plugins, CB plugin, JomSocial plugins, etc are all updated. If everything is current, you'll be fine.
