The search index could not be updated. The site is misconfigured. Contact an administrator. SQLSTATE[42000]: Syntax error or access violation: 1064 unknown table 'tiki_main_679edfb464fea' in delete request
you dont need to install anything, just enable the feature, than create some templates (tiki-admin_content_templates.php), than apply a template on the Properties tab at the wiki page edit screen
I attached an image about these steps, hope it helps
