Thank you for answer.
What you mean with "own localisation"? You mean I have finnish and english at language manager. I have.
After update language files wasn't UTF-8. Anyway, I changet those to UTF-8..didn't help.
You can try, does it work for you: www.papinniemicamping.net/index.php/fi/p...ekit/Kohde/6-mokki-6

I attached my google picture. What is wrong? I get error when I try.

Hello, are you logged on Google when you are trying it?

Hi! Yes, i'm logged in. Still get message: invalid URI. It'd be nice to have google calendar working. It's quite a mess check joomla backend every time.

On your image in "Authorized redirect URL" I see after administrator double quotes instead of slash. Please fix the URL.

Thank you so much! You, know..I don't understand about this stuff. I just "copy-paste" that from you documentation (www.artio.net/book-it/documentation#d0e444). It's also worng there (" no /)
Same thing at Vebi's reply:
