Since nobody else has answered I make a wild guess:

Does it help if you reinstall the barceloneta profile in /portal_setup ?

(disable / (re) enable the theme afterwards.

PS: Have you customized anything TTW before migration (for example in /portal_skins/custom )

After looking around, I finally found the difference. I just don't understand why it happened.

before:

Element {

}
.plone-toolbar-left-expanded .container {

width: 1170px;

}
.plone-toolbar-left-expanded .container {

width: 970px;

}
.plone-toolbar-left-expanded .container {

width: 750px;

}

<div class="container">
        <div class="row">
          <aside id="global_statusmessage">
      

      <div>
      </div>
    </aside>
        </div>
        <main id="main-container" class="row row-offcanvas row-offcanvas-right">
          <div class="col-xs-6 col-sm-3 sidebar-offcanvas">

changed to:

Element {

}
.plone-toolbar-left-default .container {

width: 1170px;

}
.plone-toolbar-left-default .container {

width: 970px;

}
.plone-toolbar-left-default .container {

width: 750px;

}

> <div class="container">
>         <div class="row">
>           <aside id="global_statusmessage">
>       
> 
>       <div>
>       </div>
>     </aside>
>         </div>
>         <main id="main-container" class="row row-offcanvas row-offcanvas-right">
>           <div class="col-xs-12 col-sm-12 col-md-3 col-md-pull-9 sidebar-offcanvas">

Is there a easy way to fix it?
