Please I need assistance to install your codoforum software on my locashost. Here's where I started

http://localhost/codoforum/install/index.php

And here's the error it gives me.

Unable to require C:\wamp\www\codoforum/sys//JsonSerializable.php
Fatal error: Interface 'JsonSerializable' not found in C:\wamp\www\codoforum\sys\vendor\illuminate\support\Illuminate\Support\Collection.php on line 13

Please I really need help

sounds like you have the incorrect database information

Your server is using an older version of php which does not support some of the features used in codoforum

Codoforum requires at least PHP 5.4 or greater

Hi,

I've upgraded to PHP 5.5.12
The app can load, attempts to install but fails with the following errors. I appreciate please help.
Thanks

Andy
