Hi,
the update of News Show Pro GK5 from 2.1.1 to 2.2.0 was leading to this error (site not available anymore):
"0"
CLASS 'JOOMLA\COMPONENT\CONTENT\SITE\HELPER\ROUTEHELPER' NOT FOUND
On Joomla 3.10.12
I reinstalled the older version 2.1.1 and now the site is working again.
Could you check the latest version please?
Rhanks
