Conflict or….

Hi, after 2 years of great work now I cannot see-access to the Viewing Events or Adding/Editing Events (under general setting page) or expand “event location detail” or event cost tickets or click the little icon calendar (under add new event).

The issue is that I have not modify-update wp or add others plugin…
Into my php log there are not errors.

The question: there is a way, a trick, a tool to understand where is the possible conflict or why I cannot expand anymore the forms?
Sorry for my bad english and thanks!!!
