On the page title, there is no space between the name of the link page and the link category.
If you visit http://www.stmatthiaschool.org/links/creative-and-fun-sites/, your browser will show the following as the page title:
LinksCreative and Fun Sites | Saint Matthias Parish School
The main links page (http://www.stmatthiaschool.org/links/) displays correctly.
I am running the latest version of Link Library (5.8) and WP (3.5.2) as of today.
This is also happening on http://sticksnstring.biz/links/, so it is not something with the theme, nor the Link Library version as this site is behind by one version (running 22.214.171.124). Maybe it is something in the settings? They are both setup to display one category at a time, no pagination, and HTML Get + Permalinks.
