Still having a timeout on EVERY posting, but success on pressing the <Post> button for a second time after the error message.

I am now getting this -

which does not require a logout, but just carry on browsing and it goes away (for a while)  
(NOTE: ignore the date on my screenshot, I happened to have caught the same error a month ago and am just using the old picture as an example)

A bit worrying that we've had no acknowledgement of the problem from Plusnet!

[#4]

Yeah the same issues are happening again. I just got a timed out when entering messages today, one about 5 min ago. And I get the session verification message EVERY time I do a "Mark all messages read".
I have never log out set so it shouldn't time me out! 

[#5]

We've an internal problem raised and are looking into it (ref: 68829) - appreciate you keeping the examples coming though...

This is  GETTING VERY ANNOYING
TWO THREE time-outs replying just now, and when I went back to the unread list there were TWO when there was nearly 20 before.

[#7]

I am now getting the "Session verification failed" error (as shown in my Reply #15)  EVERY time I click on the <Notify of replies> link.
If I then return to the <Notify of replies> it tells me "Are you sure you wish to enable notification of new replies for this topic?" each time, so the status is not being set to 'send reply' - otherwise presumably I would be getting "Are you sure you wish to disable notification of new replies for this topic?"

[#8]

Now also getting ""Session verification failed"" when using the <MODIFY> feature !
If just scrolling through a thread and then hitting <MODIFY> causes the error message to appear, then no matter how you go back and try again the error reappears EVERY TIME !
However if you click on the relevant <Reply #nn> link first, then click <MODIFY>, it works as expected !    
Edit: just a quick test of MODIFY as requested below !
Edit: a second try at modifying

[#9]

Hi all,
Any further issues seen at all? Seems to be behaving for us today, just wondering if there are any problems still. @purleigh, I know there were issues with quoting seen yesterday as well as modifying - that still happening?

[#10]

Still getting posting errors today. Had one about 30 min ago. (When I was last on here)

[#11]

Hi Matt,  
I just tried modifying my Reply#22 twice, and it worked normally.
I will try again later.
Edit: but I did get "Your session timed out while posting. Please try to re-submit your message. " when I tried to post this reply ! - so it's not fixed.

[#12]

I'm frequently get the 'Session timed out..." when selecting Quote.

[#13]

... and when clicking Modify as I wanted to add that I still get the same error when Posting.

[#14]

Odd - I am not seeing any problems with Firefox 7.01

[#15]

I, too, am using FF 7.0.1.
It seems a very random issue as to when it happens probably making it harder to track down.
Edit.wondering whether this thread should be merged with the original thread?
