Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Legacy doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The “version” attribute on the “html” element is obsolete. You can safely omit it.
Bad value “application/xhtml+xml; charset=UTF-8” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/html;”.
Bad start tag in “img” in “head”.
Bad value “https://www.facebook.com/tr?id=1403944833221935&ev=PageView&noscript=1&cd[source]=magento&cd[version]=1.12.0.2&cd[pluginVersion]=2.2.3&a=exmagento-1.12.0.2-2.2.3” for attribute “src” on element “img”: Illegal character in query: “[” is not allowed.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
