    Hi,

    Today I was updating some extensions (I didn't even notice which), when I got a blank page. Then I could no longer access the backend, all I could see was a blank page.

    I turned on the error reporting, and this is what was causing it:


    Fatal error: Cannot declare class Joomla\CMS\Form\FormField, because the name is already in use in /home/____/public_html/administrator/components/com_fabrik/classes/39/FormField.php on line 22

    I changed the name of /com_fabrik/ to /com_fabrik_/. Then I got another fatal error with the fabrik plugin, so I did the same for the plugin.

    I have now recovered the access to the backend, but the files are still renamed.

    Any suggestions on how to proceed?

    Thanks

    Hi, you did not write, how you updated Fabrik (joomla backend or github). Renaming folders is not a good idea ;)

    I would suggest to update via github the complete Fabrik package. In the future you have to update always via github.
    If it's a live site, maybe you should make copy and update this first.

    Cheers, Bianka

    Are you using a Gantry Joomla template?

    I only use Joomla to get updates. Why only in GitHub, is the extension not maintained anymore in the Joomla repositores? Renaming folders was the only way to get access again to the backend...

    Yes! And I'm pretty sure that was one of the extensions getting updated. i don't even remember seeing Fabrik in the list, but I didn't pay it much attention, so I can't be sure.

    There seems to be an issue with (some) new Gantry versions.
    Which exact Gantry template/framework are you running now?

    Gantry 5.4.36
    Hydrogen template (helium also installed but not use)

    I'll ask another person to try that suggestion you quoted (I don't want to mess up with databases xD).

    Thanks
