Hi,

I have upgraded and old Grav website from version 0.9 to 1.7. Most of it works except for one page.

Your {{ member.info }} is an array, but template tries to display it as a string.
There are several ways to fix this (like iterating the array and displaying each element on its own), but the easiest would be:

{{ member.info|join(' ') }}

I think space fits here, because you already have commas in your info strings

Actually I would like to display the “info:” array as an unordered list.

@kalimati, Beware that theme Deliver is not compatible with Grav 1.7. Template /partials/simplesearch_base.html.twig does not render assets correctly:

Filter |raw should be added.

Then something like

{% if member.info|length %}
  <p>
    <ul>
      {% for info in member.info %}
        <li>{{ info }}</li>
      {% endfor %}
    </ul>
  </p>
{% endif %}

But keep in mind what @anon76427325 mentioned about theme support
