Error in log and throwing internal errors

Server

Hi all,

I am getting this error in error logs :

Error PHP Undefined index: REQUEST_URI at /home/nacsadpmcloudco/public_html/lib/base.php#175

Which relates to this code : 

	// Resolve /owncloud to /owncloud/ to ensure to always have a trailing
		// slash which is required by URL generation.
		if($_SERVER['REQUEST_URI'] === \OC::$WEBROOT &&
				substr($_SERVER['REQUEST_URI'], -1) !== '/') {
			header('Location: '.\OC::$WEBROOT.'/');
			exit();
		}
	}

This is causing multiple Internal server errors and lots of directory cannot Load directory errors

I also have a few of these but i am unsure if this is cause by the above :

Error core File with id "3" has not been found.

Server configuration
Operating system:Linux
Web server:Cent OS
Database:MySQL
PHP version:5.6
ownCloud version (see ownCloud admin page):ownCloud 9.1.0 (stable)
Updated from an older ownCloud or fresh install:Fresh
ownCloud log (data/owncloud.log, see https://central.owncloud.org/t/how-to-find-webserver-or-oc-logfile-enable-php-logfile/808):

Special configuration (external storage, external authentication, reverse proxy, server-side-encryption):
No external, and server side encryption is disabled - server runs behind ssl certificate

Thanks in advance for your help 

Login as admin user into your ownCloud and access
http://example.com/index.php/settings/integrity/failed
paste the results here. - This shows no errors.
