ERROR plugin

Hello,
I have an error on the blogin connexion business directory, I can’t manage the members at all, and they can’t modify their profiles.

When I do “manage members” I get this message:

There has been a critical error on this site. Please check your administration email inbox for instructions. If you continue to have problems, try the support forum.

Then I get an e-mail from my site telling me that a critical error has occurred, with details of the following error:
