php_uname() has been disabled for security reasons... - MediaWiki-l

24 Sep 2020

Hi Everyone,

Our site is at https://www.cryptopp.com/wiki.

Since the Mediawiki 1.34.3 upgrade, the wiki serves each page with the
following at the top:

Warning: php_uname() has been disabled for security reasons in
/var/www/html/w/includes/GlobalFunctions.php on line
1333 
<!DOCTYPE html>
<html class="client-nojs" lang="en" dir="ltr">
<head>
...

Any ideas how to fix things?

Thanks in advance.

There seems to be a fair amount of php_uname:
