I saw someone with this same issue earlier this week, but could not find it again to see if there was a solution. This just began happening this morning. I am logged in as the admin to my account when I leave comments on my blog.
Another strange issue is that I clicked reply to a specific comment and it did not nest below. I just heard from the person I replied to and she said she did not receive the usual notifications in her inbox.
It seems to be this one post, as I replied to a comment from my today's post and it is nested, but I do not know if they received notification.
I replied from both the blog itself and from the Comments on my Dashboard I double checked my settings; I have comments nested 5 levels deep.
Along with this, my comments no longer have the different appearance from the others. They stood out with a different background on my own blog. Not a big deal, I just liked how they looked in my theme. :)
I had comments turned off for a time, but turned them back on with moderation a week or two ago. Would this effect anything?
I hope I made sense with these different issues. I tried mentioning all I can think of to help with this.
Thank you for your help.
The blog I need help with is thebirdingbunch.com.
