For the last three days when I am looking at my stats, I have found that when I click on Country position (UK) instead of going to the stats it goes to the Homepage. This happens on all my project pages. I have tried other people's pages of different countries with the same result. I also tried a different computer with same result.
Thank you in anticipation, Luigi.

Just noticed the same thing this morning.
The link text displayed when you hover over the country position looks correct, and the URL displayed by the browser also matches but the page title is "Home | BOINCstats/BAM!". So maybe an error and the default (404?) action is to go to the home page?

Appears to be a new kind of protection in the webserver where a space in the URL encoded as '%20' is seen as a dangerous control character. Replacing it with '+' solves it.

Thank you for fixing my problem, but alas there seems to be deeper ramifications to this problem. I now get my country position page
https://www.boincstats.com/stats/-1/user/list/0/200/United+Kingdom#225, but when I try to get comparison of user or click on the overtake button it goes into error mode and defaults to home page. I suspect the reason is as before.

Also this occurs when clicking on the country position in the project list

Again thank you in anticipation, Luigi

this is still not working
if you look at the country stats and click on the citizens link, you go to the home page
some countries work and some don't
the united states doesn't work while Germany does work,
https://www.boincstats.com/stats/5/user/list/0/0/United%20States this goes to the home page
https://www.boincstats.com/stats/5/user/list/0/0/Germany this goes to the citizens page

any link, that includes the country name, where that name is more than 1 word. Needs the url updated swapping the "%20" with "+"

OK, think i fixed them all.

UK is still creating a URL with an embedded space when coming from the user's project list.
e.g.

https://www.boincstats.com/stats/172/user/list/0/0/United%20Kingdom/#57

So replacing that with a "+", as you said works.

Don't suppose there's a chance of getting this fixed for the Countries listed in the Project List that have embedded spaces?
BAM! > My detailed stats > Project list > Country position

Thanks

Also fixed.

Great thank you

The gremlins are back. For the last 3 days when click on country position for the overall stats (in my case the UK) and when I get to page there is no data shown, The country position for the indivdual projects work fine.

Again thanks in anticipitation, Luigi.

And fixed again. This keeps popping up all over the place

Thanks, Working now.
