Is it just me, or today, 02/11/2017, whenever I try to reply to a post, I get an error message that reads (in bold red font):
An error occurred while trying to submit your post. Please try again.
I am using Chrome (updated to latest version) and had not had this issue before. However, I did find a work-around: instead of using the "Standard" reply, I used the "Advanced Editor" to get the message to post.
