In November 2013 I switched from Lapper 5.x to Lapper 6.x and added my Pubstat keys into the new Lapper.
I also removed the # at the beginning of the line, so all should be fine.
Because our team has moved servers this week, I had to adjust the IP address in LFS World.
While doing that, I noticed that no Pubstat data was used since November 2013.
I double checked my settings in Lapper, even created a new Ident-key to make sure all is working, but still no data seems to be used.
Any ideas on this matter?

While digging through other things earlier this week, I discovered that you need to enter your PubStat key in a different place then it used to go in.
You have to set it in the file called "myInc.lpr" and then it's working as intended.

Strange. Never had that problem, but then its maybe because I only use it for LFS Remote and for some in-game info. I don't have a website displaying any stats, so maybe that's the difference?

But just in case (!), as well as keeping it in my lfslapper.lpr file, I've added it to myinc.lpr file as you suggest. Thanks.
