Zabbix 5.0.15 on RHEL 7, cannot load Zabbix frontend with PHP72 error found in http24

[LokK]

Hi All,

I recently installed zabbix 5.015 on RHEL 7 from source and was at the step trying to initiate the frontend.
I used rh-php72 and httpd24-httpd but when I tried to accessing the zabbix frontend, it will show a 500 error.
I followed zabbix guideline and installed all required rh-php72 packages.
Looking at the httpd log it will show the following error:

[Wed Sep 29 12:48:13.635195 2021] [php7:error] [pid 60036] [client 192.168.1.6:61090] PHP Fatal error: Uncaught Error: Call to undefined method CView::getOutput() in /opt/rh/httpd24/root/var/www/html/zabbix/index.php:106\nStack trace:\n#0 {main}\n thrown in /opt/rh/httpd24/root/var/www/html/zabbix/index.php on line 106

Tried googling online seems not many people have met this error... Grateful if someone could shed some light on the matter.

Thanks and Regards.
