Hi Bernard,.
already fascinating, what a server everything reveals, if something goes wrong. The error message contains so much information that I, if I was evil, now would have saved a lot of work. :-)
By the way, I can invoke the page. The error message indicates that a write operation to the database fails, because something in a box to write, what not in there fits. The content after it comes a session to create, so that the server always know that you're there while you're surfing through the site and again put an article in the shopping cart. I suspect that it is because you're using IPv6. and the server can store only IPv4 sessions, because he is not set on it.
To verify this, let's call this link:
http://www.wieistmeineip.de/ipv6-test/There should be an IPv4 address in the form 123.124.125.126, so 4 blocks of numbers are < 256 points separated.
IPv6 you had that the last shop call < shnipp - snap > (deleted by the moderator)
am still using IPv4 on the road like most and therefore left on this page an "Absent" for IPv6
My guess is that Björn has only 15 characters to save the IP on the database and doesn't get along with your IPv6 address. The solution is so that Björn is suitable for its IPv6 database.
As a workaround, you could try to change your calculator back to IPv4. You can find details here:

Unfortunately I have thus no experience, and then therefore no success guarantee.
Best of luck.

Andreas
