CF8 update

I updated the ChronoForms8 plugins and modules, adding the "ChronoForms 8 System Plugin," but after that, it no longer works.

When I try to save a record, I get the following error: Unknown named parameter $duplicate.

I should point out that everything worked until the update, and I can't even debug it.

I'm deleting the entire folder to restore it with yesterday's backup.

What could have happened?

Thanks

Download and install the latest v8 extension installer for Joomla, over yours, does this help ?

Then you can install the system plugin

if not then enable this setting and test again: Global configuration > system > Debug > Debug system

Send me a screenshot of the error please

I think that you might have installed another Chrono extension after the installing ChronoForms, all extensions have a shared library, but ChronoForms uses the latest version, so when you install another extension the library version will not be up to date and cause an error.

I added  chronoforms_v8_system_plugin that, however, it is still present and everything works

But you did not install other Chrono extensions in the process ?

Maybe Chronomyadmin, but I'm not sure if I installed it before the update or after.Anyway, I uninstalled it.
