Remove the compilers tag from the web.config file:

<compilers>
    <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider,  Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.4.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
    <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb"  type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider,     Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.4.0,     Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4"     compilerOptions="/langversion:14 /nowarn:41008     /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
