Your question (?) is far too vague to post any response, in fact there isnt really even a question.

Hi Paul

I have a bit of an odd problem.
I use 4.1.11 and the mod was working fine but today it isn't updating the last visited message, the unread posts part is working fine. I am using Firefox.
Any ideas what I have messed up??

Nope, no idea, but things dont just stop without a reason. Have you changed something ?

Well not really, but I did uninstall the mod as it was clashing with the forum sponsors logo position. I re-installed it to allow the logo to be redesigned in the correct location, it has not worked since re-installation now I think about it.

Perhaps I need to re-install again.

Damn, had to un-install it, whatever I tried it still said my last login was at 4-31pm yesterday.

That is simply built from your lastvisit time, and would suggest you have a general forum issue or a browser cookie issue. Did you check if anyone else was affected ?

Does anyone have this mod working with a header template that has been modified?

yes but did nothing different

Another problem here.
It starts after update vB to last version (4.1.11).
Forums that marked NO for option "Index New Posts in Search Engine" in ACP are not showing when click on unread posts.

Before upgrade, everything works OK. So now, I have situation that link from this MOD show " You have 7 unread posts" but when you click on it, it show message that there is not any unread post. But yes, there are 7 unread posts in that forums with abowe selected options in ACP.

After I go to that forum and read posts, then link for this MOD finally shows "You have no unread posts".

Thats a change in the behavior of vB itself. Prior to 4.1.11 it didnt take that setting into account for 'whatsnew' searches. Until such time as I can update this to do the same, that will occur.
