The server returns Compilation Error
<p>I'm using the freebie plan on somee.com. About one month ago i first upload my asp.net website and it ran without any errors. Now i've made many change to the website with VS2010 and decide to upload a new version. But the server keep showing "Compilation Error" with message:</p>

<blockquote>
  <p>Compiler Error Message: CS1061: 'pwblog.BusinessObject.ArticleBo' does not contain a definition for 'FormatDate' and no extension method 'FormatDate' accepting a first argument of type 'pwblog.BusinessObject.ArticleBo' could be found (are you missing a using directive or an assembly reference?)    </p>
  
  <p>Source Error:<br>
  Line 61:             pagedDataSource.DataSource = articleBo.FormatDate(Articles);</p>
</blockquote>

<p>Here is my FormatDate function:</p>

<pre><code>internal Article[] FormatDate(Article[] source)
{
    if (source != null &amp;&amp; source.Length &gt; 0)
    {
        foreach (Article art in source)
        {
            art.DatePost = DateTime.Parse(art.DatePost).ToShortDateString();
        }
    }
    return source;
}
</code></pre>

<p>Actually there's no problem with the function. When I debug with VS2010 it runs well. The only difference I realize between the old one and this newly uploaded one is that I changed my MSSQL from 2008 SP2 to 2008 R2 SP2, due to the fact that I've changed my OS from windows 7 to windows 8.</p>

<p>Also, here's my web.config file:</p>

<pre><code>&lt;?xml version="1.0"?&gt;
&lt;configuration&gt;
    &lt;connectionStrings&gt;
  &lt;add name="AssignmentsFinalConnectionString" connectionString="workstation id=pwblog01.mssql.somee.com;packet size=4096;user id=pwblog;pwd=Duc123456;data source=pwblog01.mssql.somee.com;persist security info=False;initial catalog=pwblog01"
   providerName="System.Data.SqlClient" /&gt;
  &lt;add name="AssignmentsFinalConnectionString1" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\AssignmentsFinal.mdf;Integrated Security=True;User Instance=True"
   providerName="System.Data.SqlClient" /&gt;
 &lt;/connectionStrings&gt;

    &lt;system.web&gt;
        &lt;authentication mode="Forms"&gt;
            &lt;forms name="MYWEBAPP.ASPXAUTH" loginUrl="Web\Login.aspx" protection="All" path="/" defaultUrl="Web\"/&gt;
        &lt;/authentication&gt;
        &lt;authorization&gt;
            &lt;allow users="*"/&gt;
        &lt;/authorization&gt;
        &lt;compilation debug="true"/&gt;
    &lt;globalization uiCulture="vi" culture="vi-VN"/&gt;

&lt;customErrors mode="Off" &gt;
&lt;/customErrors&gt;
  &lt;/system.web&gt;

        &lt;system.webServer&gt;
            &lt;defaultDocument&gt;
                &lt;files&gt;
                    &lt;add value="index.aspx" /&gt;
                &lt;/files&gt;
            &lt;/defaultDocument&gt;
        &lt;/system.webServer&gt; 
&lt;/configuration&gt;
</code></pre>

<p>Well, I don't believe that the MSSQL cause the problem, but I don't have any other clue. About the error, there's a very long detail messasge attached, so I don't put it here. So, any advice is appreciated. :)</p>
