Getting this message sometimes when I post, any idea what it means?
"Sorry, Your request antecedents incorrect or forms authentication string does not match, Can not submit"

I have never seen that one???

Probably cause your string doesn't match.

You definitely need matching strings.

I get that error when trying to post on a mobile device, not been able to post at all on mobile due to that error.

I've seen this a few times and think it is to do with other people posting at the same time - but could be wrong!

I've had this happen several times.  What I do is.....
Copy the text that I have already typed.
Reload the page.
Then paste the text back in and post.

This seems to work for me every time.

As a matter of fact...it just happened...and I did what I just posted.

You're right for the solution. Kept getting same response until I tried your method. It works! Thanks.

It's genetics.  It's all the fault of your antecedants.
