Okay so it has not only been me having issues leaving comments this past week. Today I have discovered two things....
1. is that I could leave comments on blogs that had the pop up comment window (I have also discovered how to change mine to this as I like this layout better when I am leaving comments and hope my followers do to).
2. Tracey from Trace-elementz posted today that if you un-click the stay logged in button when signing in it will allow you to post comments also. Between these two things I am on a roll! Thanks Tracey.
I hope everyone else finds this works for them too if they are still having troubles.
