Hi @toni_bodonji,

Can you check using the RWD theme (the default one) first?

Also, if there are 3rd-party modules maybe you could try disabling all those modules.

The idea is to find if the problem is within the theme or some module first.

Hi @Damian Culotta,

Thank you for replying.

I received this error when I tried to create new shop inside magento and I went to Queldorei/shopper and then Activate theme (to the created shop). I was thinking that by doing this, it will create default pages for a new shop and set up proper folder architecture so I do not have to make changes manually. 

So I do not think it is module issue, but this step that I have done. 

I am beginner in magento so sorry for my ignorance.

Today I deleted that shop and created another one, step by step and that error is still there.
