Hi there,
Firstly, I think it's important to note that the tool isn't telling you that the site has canonical issues. Canonical issues are basically when you can view the same page from more than one version of the URL.
The "too many links" issue is, as it suggests, the page has too many links.
At the moment the homepage (http://www.texaspoker.dk/) has 102 links, which is acceptable however you should look at removing any unnecassary links on-page. Generally, you should look at having few than 100 links on a page. Having 102 is fine but obviously if you can remove unnecessary links, do it.
The fewer links on the page the better
Hope that helps/clears things up!
