The debug info shows "Link record 0 (0)" and I'm sure our site has a few dead links that show as page not found.
"Check each link" is set at 24 hours and advanced Link monitor items are all unchecked. I'm confused by these - are they two different features?
I tried the Forced recheck and there are no results.
At the dashboard, it shows Loading and seems to hang with:
No broken links found.
No URLs in the work queue.
Searching your blog for links...
Thanks for all suggestions.
