"Are you saying that the related posts section is appearing and disappearing on a given post?"
Yes - I was mostly checking randomly, but here's a few of the links
contains a link for a commercially-available product which should surely generate related links, and has before - right now though (09.56)it isn't showing any at all. Nor are any of the above posts, and several other that I've looked at.
"That being said, related posts shouldn't appear and disappear on the same post when refreshing the page and/or using a different browser. I am not clear if that is what you are saying is happening or not."
Indeed, that's exactly what I'm saying (I use IE to check stuff like this, as it's not normally used for anything else - the effect is the same as getting someone else to check for me; Firefox would "recognise" me and not show me the related posts). And yesterday evening,shortly after my last post here, they were showing again on a random check with IE, and around that time my stats picked up dramatically, ending the day at 152 hits, having been pretty static most of the day. Go figure.
My hits do vary throughout the day, like anyone else's but when they're stuck on 25 hits, 2 or 3 referrers and nothing from search engines, for half the day, then it's so far outside the norm that something is clearly out of whack.
I accept that the content of some posts may not generate related hits, though given the eclecticism of the web it would be a rare post indeed that was unique, and had no matches. raincoaster says, as you can see, that staff say it's normal for related links to come and go, yet you say it's not. I'm intrigued.
Apologies for the delay in replying - I'm disabled, and not generally up to much in the evening.
