Empty CMS page in Back & Front Office Multi-shop Prestashop 1.6.1.11

[lovemyseo]

I have recently update my shop http://biophoretics.com  from  PS 1.6.1.10 to PS 1.6.1.11
 

Then created Multi shop with following links http://ion-exchangeresin.com/  and http://biophoretics.com.mx Once I created the multi-shop everything seems to be working fine except CMS page in front and back end are empty for main shop its fine but in back office pages are listed there but empty no data .
 

I feels like there are seems like some fields missing in database as I tried to ad data to one page and it gave me an error

Can I use this tutorial ?  https://www.templatemonster.com/help/prestashop-1-6-x-troubleshooter-changes-are-not-saved-in-cms-pages.html#gref
