Check out my new Security, Auditing, Monitoring and Backup service for Joomla - myJoomla.com
It has come to my attention that mosKnowledgebase, after upgrading to Joomla 1.0.10 and under specific circumstances wil display the following error:
Template ‘frontpage-ending’ does not exist.
We run Joomla 1.0.10 and moKB on our site but could not replicate the issue until today when we had access to a customer site.
The problem _may_ be related to having multi-lingual components (like joomalfish/mamblefish) installed – although I was unable to prove this beyond all doubt.
The quick fix for now is to edit /components/com_kb/kb.php around line 435 and remove completly the following line of code:
if ($OverrideCols) $cols = $OverrideCols;
There is no problem removing that line of code as it actually doesnt do anything anyway and was scheduled for removal in the next update.
