SOLVED : 500 error acessing shop after upgrade 1.5 -1.6

[pat123]

I upgraded from PS 1.5.6.1 to 1.6.1.12.If I want to acces the shop I get a 500 server error.(shop is not in mainteance mode)

 

I applied fix described in  this blog (https://www.prestashop.com/blog/en/the-500-internal-server-error-explained-solved/ )(versions above 1.5.3

 

Now I get he error (see screenshot)

 

What's does that mean ?

 

find it!

 

default-theme was called default-bootstrap (dir themes) renamed it to default.

 

Shop layout is not what it should be.

 

thanks
