Error running Webconfig

[philchudley]

Hi All

I have installed version 4 of PCS on localhost and have configured IIS with PHP, and confirmed that PHP is working with IIS.

The installation went smoothly and I have copied WebEA and WebConfig to c:\inetpub\wwwoot

Firewall inbound rules are fine, however when I try to navigate to localhost/WebConfig I receive the following:

Fatal error: Uncaught Error: Call to undefined function mb_strtolower() in C:\inetpub\wwwroot\WebConfig\globals.php:179 Stack trace: #0 C:\inetpub\wwwroot\WebConfig\globals.php(26): strIsTrue(false) #1 C:\inetpub\wwwroot\WebConfig\globals.php(14): Logging->__construct(false) #2 C:\inetpub\wwwroot\WebConfig\index.php(31): require_once('C:\\inetpub\\wwwr...') #3 {main} thrown in C:\inetpub\wwwroot\WebConfig\globals.php on line 179

Any ideas?

Thanks

Phil
