I have no idea about web development or writing code. However, I used my common sense to replace my domain's credits in a free blogger theme.
The attached picture shows what I exactly wrote:enter image description here
And here is what the error message says:
org.xml.sax.SAXParseException; lineNumber: 3748; columnNumber: 3; The element type "div" must be terminated by the matching end-tag "".
Could someone explain simply how I could fix this?
