broken blog page
I had a blog page on my framasite, but it's broken. It shows:
Sorry, something went terribly wrong!
400 - Template "partials/breadcrumbs.html.twig" is not defined in "blog/bootstrap/blog_theme.html.twig" at line 7.
For further details please review your logs/ folder, or enable displaying of errors in your system configuration.
If I try to add a new blog page, I get the same message.
How can I solve this? Thanks.
