title: Internal Server Error with template / Livelink WCMS 9.5.1
body: <p>i just ran into some serious problems with a historic Livelink system - WCMS-Server 9.5.1.
  I added a JSP-Topic secondary to another using the same template that prevails at the parent topics. Even though they work great with the parent topics, i can't find out why i get an Internal Server Error 500 when trying to preview them in edit-mode. Secondary Topics have basically the same settings. 
  Same for JSP-Page. Can anyone help? Thanks in advance,
  Michael</p>
