Warning: A DOCTYPE is not allowed in content at line -1
10:28 PMYou usually get this error message when you try to define a DOCTYPE for your Visualforce page. To give a brief description, there are two types of DOCTYPES (Strict and Transitional). Your Visualforce Page are pre-defined with a DOCTYPE, and you cannot override them. I am not sure about the use of DOCTYPES, and i have not encountered a situation to override them.
So, do not include the below line of code in your Visualforce page and the error disappears.
