I just recently downloaded wordpress during the first download i had a problem with hosting.. after i talked with them everything seemed going well but after completing process this error.

what should i do? i’ve watched youtube videos to check what is in line 61

and it shows this : $this->widgets[ $widget ] = new $widget();
}

also i’ve tried another version of wordpress and reupload it 2 times but for what i understood something it’s still missing .

how can I solve this?
thank you for your help in advance
