Unknown entity name Web Standard

Description

An unknown entity has been used. This often happens when &param=value is used instead of &param=value in URL query strings.

Help

In HTML the ampersand character (&) is reserved for marking character entities so you should never use raw ampersands in HTML - including ampersands inside URLs. Any URL that uses an ampersand should look like: file.php?var1=val1&var2=val2
