Hi,
Thanks for your speedy reply! The discussion on the Stack Overflow forum is interesting. The problem is very similar though I do not have enough information to affirm that they are the same.
In our case, all URLs were redirected to domain-name/blog, even though “blog” does not appear in any of the slugs.
As to what provoked the error, I had done a Linux update in the morning though I cannot say that this created the error.
