    @alweisenborn. Thanks so much for posting this error. I just posted version 4.0.2 of Easy Folder Listing Pro, which fixes this. Please update to the latest release. Thanks.


    Hello Michael,

    The problem is fixed. Thank you for the rapid resolution!

    Best Regards,



    Hello Michael, i installed version 4.0.2 of Easy Folder Listing Pro on joomla 4.0.3 and the content part seems to work now, but still get this error when i use the module : Class “ValorApps\Module\EasyFolderListingPro\Site\Helper\EasyFolderListingProHelper” not found


    Hello Michael, the error , “ValorApps\Module\EasyFolderListingPro\Site\Helper\EasyFolderListingProHelper” not found seams to be a case sensitive problem. helper is saved as :
    and also the case of the directory’s don’t match, as from the moment that u run this on a linux platform it will fail.

    @mvdhome. Thanks so much for posting. This case sensitivity issue has been really frustrating for me as a developer. I have tested my code on a number of systems: Mac OS X (locally), Windows 10 Pro (locally), and Linux (hosting company), and did not encounter any prior issue before release. I would never knowingly release my code with errors that show up as soon as you click on Dashboard or use the front-end module.

    On top of that, PHP is case-insensitive with regards to namespaces, based on their documentation. Also, PHP developers have known this for years. However, it seems to be related to auto-loading in Joomla. Prior to Joomla 4, this was not an issue.

    Anyways, I will have this fixed for you shortly.

    Thanks so much to you and others who have been reporting this, and even giving some detail and allowing me to access your backend administration. I really appreciate this, as I am unable to replicate these errors on any of the systems available to me.

    What I would appreciate is if persons who encounter this could provide me with a spec detail of their servers so that I can maybe setup a test system to use going forward. Information like your OS details and version/build as well as your PHP versions, Apache (or other web server) details. If I could setup a test system that acts like your environments, then I can catch these errors before releasing my code.

    Thanks so much, everyone.

    @mvdhome. Ok. I have released version 4.0.3 with the fix to the Module. For your reference, it was not a reference to the Helper that you thought in the administrator backend.


    GR8 job Michael, it works now
    brgrds, Marc
