    Unknown server tag 'uComponents:RenderTemplate'.

    Templates and document types

    Hi, just upgraded to 4.7.1 from 4.9.1 and the back office seems to be working ok however when I wish to view my web site I keep getting "Unknown server tag 'uComponents:RenderTemplate'"  error from templates tags.

    Thanks

    Hi Sami,

    Do you know if anything was removed from your templates or Web.config during the upgrade?

    If so, then you might be missing a reference to the RenderTemplate server control.

    Either in your template add this towards the top:

    <%@ Register Assembly="uComponents.Controls" Namespace="uComponents.Controls" TagPrefix="uComponents" %>

    or, add it to your Web.config, (under the "/configuration/system.web/pages/controls" section):

    <add tagPrefix="uComponents" namespace="uComponents.Core.Controls" assembly="uComponents.Core" />

     

    Failing that, take a read over this topic - contains info about upgrading past Umbraco 4.8 with uComponents: http://j.mp/umb48-breaks-ucomponents

    Cheers, Lee.
