How can I fix this problem in the message box?

Its display as "important massages" in the Search Engine Ranker. it reads:

"2019-02-26 09:50: No target to publish (perhaps blocked by search engines, no scheduled publication) [first appeared at 2019-02-26 09:46]"

What does it mean?

I ran the program from time to time a few days.

It shows 71 submitted and 4 verified … no information on the Nofollow and DoFollow links.

I think the same program has had different showing results before.
