Fatal exception of type "Error"

[Nicholas Basile]

I've installed the Widgets extension per the instructions on the page: https://www.mediawiki.org/wiki/Extension:Widgets and no matter which widget I try, I get the "Fatal Exception of type error".  

The current two that I am trying is the Steam widget and the Discord widget.  I created a page, https://wiki.megateamfortress.com/Widget:Steam with the contents: 

<noinclude>__NOTOC__

This widget allows you to add a link to your Steam profile and your current status.

== Using this widget ==

For information on how to use this widget, see [https://www.mediawikiwidgets.org/Steam widget description page on MediaWikiWidgets.org].

== Copy to your site ==

To use this widget on your site, just install [https://www.mediawiki.org/wiki/Extension:Widgets MediaWiki Widgets extension] and copy the [{{fullurl:{{FULLPAGENAME}}|action=edit}} full source code] of this page to your wiki as page '''{{FULLPAGENAME}}'''.

</noinclude><includeonly><a href="http://steamcommunity.com/id/<!--{$id|escape:'urlpathinfo'}-->" target="_blank"><img src="//steam.random-host.com/profilesig/<!--{$id|escape:'urlpathinfo'}-->.png" style="border: 5px solid #0e1e1e; -moz-border-radius:.5em .5em .5em .5em; -webkit-border-radius:.5em .5em .5em .5em;"></a>

</includeonly>

This page creates successfully.

Then, I go and add the code: 

{{#widget:Steam
|id=Manyman
}}

to a page and get the following error:

I get the exact same result with the DiscordApp widget.

Looking on the site here, I noticed that this guy: https://groups.google.com/forum/#!topic/mediawiki-widgets/v-CmKlFiscw has the same exact problem I have.  

Why is this happening?

Also, I'd like to note that if I change the code to: 

{{Widget:Steam

|id=Manyman

}}

then all I get is:

without an error... but all that shows up is the html code.

Just bumping the thread.  It's been months since the post and I've seen no replies.  Is this thread monitored anymore?
