Your server is misconfigured. When a user agent which sends the user- 
agent HTTP request header used by Checklink requests http://www.1a- 
geschenkidee.com/ it claims "An appropriate representation of the  
requested resource / could not be found on this server." despite  
being perfectly capable of doing so given exactly the same request  
headers but with a Firefox user agent.

This is probably an attempt to block bots from the site (with a very  
wide "No libwww-perl based user agents" block), and since Checklink  
is a bot, it gets blocked.
