HelpGuru – KnowledgeBase returns blank results page

Hi,

i′m using the HelpGuru Theme & Knowledgebase along Relevanssi.

The built in Search Box works pretty fine with Relevanssi, but hitting the “Show more results”, which should show a results page, shows a blank page with the term “Search for”.

Someone any idea or experiences using HelpGuru and Relevanssi?
