Oyster theme lost side bars

I have recently installed woo commerce to my site http://www.worldtravelphotos.co.uk/ and have lost the side bars to the about and contact page , the side bar to the shop page appears at the bottom and not on the right as required. The only other recent change was an addition of a Luna/photography plugin . I have limited WP knowledge so would appreciate any help

Hey Dave, better contact the author/seller of the theme, and ask for support. I’m sure they can give you quick assistance and bugfixes

Hi Theme SLR ,
unfortunately my support has recently expired and $42 to renew could prove an expensive fix to what is other wise a smooth running theme,
