Hello, I have read numerous forums on this issue and is seems each case/resolution is specific to the persons file. I have the same error, but can't find where it is coming from. This is from a wordpress site I did not create - this just appeared out of nowhere without anyone editing the file. I have attached a screenshot of the error. I did add the ob_start(); per a forum I found and it did get rid of a different error about the header. Any help would be greatly apprecated!
