Fixed this on my locahost by changing this :

<em
  t-attf-class="d-block text-center text-muted small my-#{len(providers) if len(providers) &lt; 3 else 3}"
>- or -</em>

by

<em
  t-attf-class="d-block text-center text-muted small my-#{len(saml_providers) if len(saml_providers) &lt; 3 else 3}"
>- or -</em>

Just checked, that does not apply to 16.0, the merged fix is already present for version 16.0.

I don’t have the right to change the issue, but it should be changed to solved.
