Have a nice day Gregory
Thank you very much for your reply and for the tip 🙂
If the error happens next time I will try to disable user related role plugins or admin menu plugins..
Thanks again have a nice day
Have a nice day @webitman
I just checked my admin section and I can confirm that the error disappeared for me and all data in Cerber Traffic inspector is displayed… I think it was related to some upgrade of some modules on Cerber Traffic server, but it’s hard to say 🙂
