    Cannot perform runtime binding on a null reference

    Hi,

    I upgraded an Umbraco 4.5.2 website to Umbraco 4.7, but apparently Razor scripts don't work. Everytime I try to run a page that has a Razor script, I get this message:

    Cannot perform runtime binding on a null reference

    Anyone familiar with this problem? And how can I solve this?

    Thanks for your help,

    Have you tried writing something harmless like:

    <umbraco:Macro runat="server" Language="cshtml">
      <p>Hello world</p>
    </umbraco:Macro>

    Have you copied the new web.config entries marked with "added in 4.6.2"? And there's a few new things in the umbracoSettings.config file as well.

    Hi Sebastiaan,

    Thanks a lot, your advice solved the problem. The problem was caused because I didn't replace the web.config file during the upgrade process. I tried to at first, but when I surfed to the site, the install wizard started. Because it wasn't clear if the wizard would do an upgrade or a complete reinstall, I didn't take the risk and moved back the old web.config file.

    Now I copied the web.config of the Umbraco 4.7 build and let the install/upgrad wizard do it's job, and luckily it just did an upgrade of my Umbraco installation. I checked everything and now even Yannick Smet's excellent multilanguage tools works. You really make my day :)

    See you at codegarden,

    Anthony
