Cannot save settings form after upgrading to 3.x

This problem also occurs in D9.5 Thunder with the Seven Admin (enhanced) theme. Many of the optional settings are hidden by default, but required, so they often prevent saving the settings form.

For example, if a user were to choose the regular Dropdown that does not include settings for flag icon, size and display options, and attempt to save, the settings cannot be saved. The user must choose among the different display options and set all of the options for all of the optional displays before settings can be saved.

Hi,

Try to reinstall, I believe the default values are not imported during update from older versions.

Thanks!

that was totally it.

so the update from older versions doesn't quite work.

Uninstalling and reinstalling does.

Not quite sure if this needs an update hook or just an explanation on the module page and Readme.

Hi everyone! 👋

In my opinion it absolutely needs an update hook for those updating the module. Besides the frustration of facing a WSOD after updating the module, it's bad user experience, which doesn't make justice for such a great module with over 10k users!

It does deserve a seamless upgrade path to its D10 compatible version.

I'll try to work on providing an update hook today.

I'll keep the thread posted.

Attaching a patch with a temporary, minimal "fix" that will import the default configuration from config/install in a hook update (Also created a MR for it).

Ideally, we would have a more sophisticated process of copying over the previous configuration entries over to their new names, whenever there's a 1-to-1 match.

Unfortunately I don't have the time to work on that now.

Importing the default config is wrong, the old config must be migrated. This is what is done in 🐛 Errors after upgrading to 3.0.1 from 1.14 or 1.15 Needs work
