first you should edit your post (insert the deleted bracket by the end tag of the link…)
as the screenshot sais, there's some overfloving text on page 1 of your document. take a look at the text frame – maybe it's only an empty line…
if you just ignore the error, without checking it, you could end up with a .pdf file withsome missing text…
