Report Shows a broken link coming from the generator

[shelly]

Hi.  I just purchased and set up this program yesterday.  I ran the script yesterday and got no 404 errors.
This morning, though, I got one:

1 broken links found!
View the list: [ External links are visible to forum administrators only ]

How do I fix this and why is the generator generating broken links?

Thanks

Hello,

you should open a page from "Referred from" column, find a link that is displayed as broken and correct or remove it.
