Hello
Ideally you will need to update your template to the latest download, however as you have made changes to the core template files, such changes will be lost if you upgrade. We amended the issue by changing some template files manually to the latest download.
I have enabled the menu in the
hornav module position, however, this brings to light an issue with your Joomla installation...
0 - Using $this when not in object context
This error is present regardless of the template enabled so is unlikely to be template related. You appear to have a large number of plugins enabled. May I suggest disabling any plugins you are not using and see if this resolves the issue. Ensure you have the latest download of the remaining plugins installed.
