IE8 throwing "Array length must be assigned a finite positive number" and "Object doesn't support this property or method" errors


#1

I’m trying to integrate a Twitter sharing button into my site and am running into errors with Internet Explorer 8.

Specifically, IE8 throws two errors: “Array length must be assigned a finite positive number” and “Object doesn’t support this property or method” which cause the widget not to render properly.

This is in Internet Explorer 8.0.6001.18904 on Windows Vista.

It throws the error on any of the search result pages on my site, Lean Domain Search:

Here’s the code I’m using the embed it, which was taken directly from Twitter’s official button generation page:

			<a href="https://twitter.com/share" class="twitter-share-button" data-url="http://www.leandomainsearch.com" data-text="Check out Lean Domain Search, a fast new domain search tool" data-via="mhmazur">Tweet</a>
			<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>    

Here’s a screenshot with the area where the Twitter share button is supposed to show up shown in red:

Here’s the full error message:

What can I do to fix this?

Twitter devs, any word on what’s being done to address this issue? I believe I followed the instructions correct which, if true, suggests that a lot of people are also experiencing this issue.

This issue should now be resolved; let us know if you’re still seeing the problem with IE and this particular error.
