Internal Server Error: missing method or closure Receiving the standard error:


  Craft\MatrixBlockModel and its behaviors do not have a method or
  closure named "sectionArticles".


The problem is that this error doesn't make sense. Here is why:


I have a newsletter template with the block 'sectionArticles'
It lists entries from 3 different sections
These 3 sections do not have a block 'sectionArticles' nor a reference to it in their templates.
If I click on a link that leads to the url for these entries, I receive the above error
If I copy and paste the url into a new tab everything is fine
This only recently started happening. In other words, old issues of the newsletter are fine


Help?

Here is code for referring template:

{% for block in entry.connectionsContent %}
  {% switch block.type %}
    {% case "connectionsTextOnly" %}
      &lt;div class="{{ block.backgroundColor }} page-section"&gt;
        &lt;div class="row"&gt;
          {% set asset = block.sectionImage.first() %}
          {% if asset %}
            &lt;div class="large-3 medium-4 small-12 columns large-push-9 medium-push-8"&gt;
              &lt;img src="{{ asset.url }}"&gt;
            &lt;/div&gt;
            &lt;div class="large-9 medium-8 small-12 columns large-pull-3 medium-pull-4"&gt;
          {% else %}
            &lt;div class="small-12 columns"&gt;
          {% endif %}
              {{ block.sectionText }}
            &lt;/div&gt;
          &lt;/div&gt;
        &lt;/div&gt;
    {% default %}
      {% set entries = block.sectionArticles %}
      {% if entries | length %}
        &lt;div class="{{ block.backgroundColor }} page-section article-grid"&gt;
          &lt;div class="row large-up-4 medium-up-2" data-equalizer data-equalize-on="medium"&gt;
            {% for entry in entries %}
              {% if entry.section.handle == "news" %}
                {% include 'news/_includes/feed' %}
              {% elseif entry.section.handle == "pages" %}
                {% include 'pages/_includes/feed' %}
              {% elseif entry.section.handle == "events" %}
                {% include 'events/_includes/feed' %}
              {% endif %}
            {% endfor %}
          &lt;/div&gt;
        &lt;/div&gt;
      {% endif %}
    {% endswitch %}
{% endfor %}


The feed templates are just links and display fine.

The errors occurs on the events/_entry, news/_entry and pages/_entry templates. There is no references of the block 'sectionArticles' in those templates.

One more thing: the error only happens on scheduled entries, where the Post Date is in the future, after the Post Date has arrived.
Thanks everyone for taking a look. I forgot that I had implemented something on the receiving templates that allowed you to navigate between articles from the newsletter, if the referral url was the newsletter. After I implemented the text only block, I forgot to change this to ignore those blocks.
