It's been a long time since I installed Joomla_4.0 (from its beta version therefore ).

I'm learning that Regular Labs updated the plugins I use;

  • Articles Anywhere (plugin more compatible since joomla_4.0)
  • Anywhere Modules
  • Cache Cleaner
  • Anywhere Modules
  • The only plugin that does not have an update (Tabs) is available in development version
    https://regularlabs.com/development-releases

I am trying to update: I have the following error

Argument 2 passed to RegularLabsInstallerScriptHelper::preflight() must be an instance of JAdapterInstance, instance of Joomla\CMS\Installer\Adapter\LibraryAdapter given they advise to physically uninstall the plugins before updating them.
Reading on the forum of

This means deleting the associated directories on the server:

Regular labs

rm -rf administrator/components/com_regularlabsmanager

rm -rf libraries/regularlabs

rm -rf plugins/system/articleanywhere
rm -rf plugins/system/componentsanywhere

rm -rf plugins/system/modulesanywhere

rm -rf plugins/system/tabs

rm -rf plugins/system/sliders

For plugins components recalcitrant to uninstall I delete them directly in the database (table jooxx_extensions)


I also disable the plugins drop-down panels and tab

{tab Mentions Légales|green|alias:mentions-legales}


and I launch the update => success

{tab Mentions Légales}


For tabs Regular labs provided a workarround while waiting for the update
