grazie....codice:This page is not Valid (no Doctype found)! Below are the results of attempting to parse this document with an SGML parser. 1. Error Line 1 column 0: no document type declaration; will parse without validation. <script language="JavaScript" src="http://www.gvisit.com/record.php?sid=612bf8c2 ✉ 2. Error Line 4 column 2: "DOCTYPE" declaration not allowed in instance. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.or ✉ 3. Error Line 5 column 42: document type does not allow element "HTML" here. <html xmlns="http://www.w3.org/1999/xhtml"> The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed). One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error). ✉ 4. Warning Line 111 column 46: cannot generate system identifier for general entity "igrave". ...!-- #BeginDate format:fSw1 -->Martedì 19 Settembre, 2006<!-- #EndDate An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (;). The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs". Entity references start with an ampersand (&) and end with a semicolon (;). If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters. If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem. Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.
