Upgrade from 5.1.4 to any version leads to design failures

If i upgrade to any other version than 5.1.4, plone loose the site navigation.



No idea where to change the configuration to get back the site navigation.

Hope someone can help me.

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 )
