Severity: Core Warning Message: Module 'mysqli' already loaded

Question

I was developing a website via localhost, everything was working well, but I just uploaded the website online, everything else seems to work well except this sticky message below my footer : `

 A PHP Error was encountered

Severity: Core Warning

Message: Module 'mysqli' already loaded

Filename: Unknown

Line Number: 0

Backtrace:

`

Its showing line number 0, I have no idea what this means. If this can be fixed, How? and if so, is the problem from my side or my hosting providers?

Answer 1

Follow these steps:

1) Controller class name should start with capital.

2) Filename name should start with capital.

Because Linux is case sensitive.
