Hello and thank you for choosing just answer.
So, just so I understand....you were logged in at wordpress, and you did a suggested update, and now you are in an endless loop unable to post or comment.
I may need to have to do a remote session, so I can see exactly what you are describing....as it could be number of different things. Especially since you are not sure WHAT update you ran.....only that it was suggested.
Would you mind doing a remote session?
Sure...just come on back when your ready. I will be here.
Sure thing....your welcome.
