Visitor’s remark: error at “Decent Jokes” site. No contact…

Hi… for what it’s worth
(not sure if this is the way to get this problem under the right people’s attention… if there is any way… – anyway)

At https://www.decentjokes.com/ (powered by wordpress) I can search the database (and get results ?? but get an error after clicking on any of the links presented:

=========
Not Found
The requested URL /category/yo-mama-jokes/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/1.3.34 Server at https://www.decentjokes.com Port 80
=========

I use Firefox… but get the same result with Internet Explorer:
HTTP-fout 404 – File not found.

There is no contact address at the site or at wordpress itself… so no way to contact the site owner… Little sad for him/her to put so much work in a site which’ content is not available.

So… decent jokes owner… or anyone who knows him… if you read this… you might know what to do :).

ps A webmaster contact address is always appreciated ;).
