I have just installed CentOS 7
and installed LAMP and have downloaded Joomla and extracted the zip and granted permissions to folders etc. If I navigate to localhost I get an error of
JHtmlBehavior::polyfill not found
What is causing this error to be displayed? This is a fresh OS install and a fresh Joomla install
EDIT
I am running php 7.1.4 & CentOS 7 & MariaDB
