The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.
The “width” attribute on the “table” element is obsolete. Use CSS instead.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
Duplicate ID “__mcenew”.
Bad value “auto” for attribute “width” on element “img”: Expected a digit but saw “a” instead.
Bad value “auto” for attribute “height” on element “img”: Expected a digit but saw “a” instead.
Attribute “type” not allowed on element “textarea” at this point.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
