please help me

solved database error. ,same error, now my websites are working, but still can’t access to cyberpanel

Could you resolve the error? I currently have the same error and I don’t want to lose the information. it stays in an infinite loop and I don’t know how to stop it. I appreciate if you can tell me how you solved that error

Dear Users,
I am getting some errors "when I click on all websites, there is no preview instead showing an error

“No Screenshot available”
500 Internal Server error

Why it is showing on all websites, however, the websites are running ok, I have checked it on gtmetrix and google page speed, websites are working fine, secondly, after installing Cyberpanel my traffic is decreasing day by day and alexa rank is hit badly.
