Error occurs when inserting google tag manager code to blogspot template:
Error parsing XML, line 1999, column 45: The reference to entity "l" must end with the ';' delimiter. Hide notification
How to fix:
Change this (third) line:j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
To:
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
