To avoid CORS errors, following configs needs to be added to fully CORS-enable an Apache web server in <Directory>, <Location>, <Files>, <VirtualHost> of /etc/httpd/conf/httpd.conf or .htaccess
Header set Access-Control-Allow-Origin "*" Header set Access-Control-Allow-Headers "*" Header set Access-Control-Allow-Methods "*"
To ensure that your changes are correct, strongly recommended that you use
apachectl -t
to checck your configuration changes for errors. After this passes, you may need to reload Apache to make sure your changes are applied by running the command
sudo service httpd restart
