TYPO3 Backend Error VHS ResourceViewHelper

I updated a TYPO3 Installation from 6.2. to 7.6 and now I have the problem, that I always get an error after clicking on the Page Settings. I always get:

Could not analyse class: "Tx_Vhs_ViewHelpers_Extension_Path_ResourcesViewHelper" maybe not loaded or no autoloader? Class Tx_Vhs_ViewHelpers_Extension_Path_ResourcesViewHelper does not exist"

Some relevant Extension in the installation:

  • crawler
  • fluid
  • fluid_styled_content
  • fluidcontent
  • formhandler
  • ke_search
  • news
  • realurl

Maybe someone of you have an idea why this appears only at the page settings

Solution

  • That is because at least one template is rendered (or at least parsed) where you use the VHS ViewHelper ResourcesViewHelper with its old class name from the pre namespace era.

    Scan your fluid templates (most likely page templates) for the old VHS namespace declaration

    {namespace v=Tx_Vhs_ViewHelpers}

    and change it to 

    {namespace v=FluidTYPO3\Vhs\ViewHelpers}

    You can also switch to declaring the namespace in the HTML tag like this:

    <html
    xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
    xmlns:v="http://typo3.org/ns/FluidTYPO3/Vhs/ViewHelpers" 
    data-namespace-typo3-fluid="true">
