Erros trying to add content

I'm trying to add a content with an user but FlexiContent is showing lots of errors and warnings. Did someone know s about it?

See attachment.

Hello

you can fix the error by:
1. logout and re-login in backend
2. and then visiting the backend Flexicontent dashboard

the error is due to the new support for form layouts per item type,
the new item form fields are not assigned to new types when you create a new item type

or use this new version:
github.com/FLEXIcontent/flexicontent-cck...efs/heads/master.zip

Thanks for you fast feedback!
In fact I did it sometimes... The problem keeps happening...

The version I'm using is the last one (4.0.2). Which version is this you mentioned the link?

To use this version you put the link, I will need to reinstall the plugin or it is compatible with 4.0.2 db?
I'm asking because I created lots of items, categories, types, configurations, etc... I would be really bad to redo it...

no just install it that do an update
1 install new version
2 save your type
3 logout
=> error will desepear
