Website builder - problem with <div class="oe_structure">
I builded a website in odoo using visual builder. Everything worked fine until I had to move whole view code to a new one. From this moment the visual builder is not working properly - I can not insert a block on whole site, but just on the footer area. I noticed that <div class="oe_structure"/> is responsible for this, but if I put it on very top of code right behind <t t-call="website.layout">, blocks can be insert only on footer, if I put code somewhere else for example between <section/><section> then I can insert blocks just between this section.
Where I should insert that div?
