Get lots of errors in my apache error log.

I’m not sure this is completely related to this plugin but I have some strange behaviour on my site.

The site is https://www.planetrail.co.uk/

On the second menu (dark blue) you will see ‘Holidays by Rail’, ‘Destinations’, ‘Holiday Ideas’ and ‘Seasonal’. All work fine except Destinations – if I select a sub category item from any of those menu’s it’s OK. However if I click the menu heading (‘Holidays by Rail’, ‘Destinations’, ‘Holiday Ideas’ or ‘Seasonal’) I should just get the one post in than category (and no posts from sub categories – I use a plugin to hande that).

If I click on Destinations I also get the three posts that are in the sub category of United Kingdom but not those from other posts in sub categories – weird.

I’m puzzled – any ideas?
Thanks.
