I went exploring around my hosting control pannel and they had a custom error page setting. &nbsp;It does a different job to when there is a missing aspx file. &nbsp;The local host seems to be catching all the errors with just the web.config, however my problem was on the server.<br />

I didn't realise that a URL required an extention. &nbsp;

I went exploring around my hosting control pannel and they had a custom error page setting.  It does a different job to when there is a missing aspx file.  The local host seems to be catching all the errors with just the web.config, however my problem was on the server.

I didn't realise that a URL required an extention.  

<div>
<div class="content wysiwyg-content">
I've added whats required in the web.config file<br />
<br />
&nbsp; &nbsp; &lt;customErrors mode=&quot;RemoteOnly&quot; defaultRedirect=/DefaultEr<wbr />ror.aspx&quot;&gt;<wbr /><br />
&nbsp; &nbsp; &nbsp; &lt;error statusCode=&quot;404&quot; redirect=&quot;FileNotFound.asp<wbr />x&quot; /&gt;<br />
<br />
This works fine for whenever i try to type in a webpage with a .aspx extention that doesn't exist. &nbsp;However, if i just try to type in &quot;mysite.com/stuff&quot; then it doesn't seem to trigger the 404. &nbsp;Does anyone have an idea why? &nbsp;Thanks.

404 not working for a non .aspx extention
