Erros trying to add content

Thanks! But it didnt work also.
I just installed the version i said (4.1.0b1). Visited the dashboard. It asked me to update index in database and I did it.
So I logout in admin, login again.
Did the same in the user area. The problems keeps happening.
Do I need to remove all my types and recreate them?

I tried adding all item types to form fields. But It didnt solve the problem too.

Hello use confidential tag to send me an access

Hello

did you click to restore the default item form layout configuration
- at the component configuration
- at the item type configuration

(do the above for both backend and frontend item from)

The message is warning you of wrong configuration

ggppdk, where do I find this?

1 global configation (flexicontent) => item form => set tabs (default) for front-end and backend)
2 check all types => item form => set tabs (default) for front-end and backend)
