array_merge(): Argument #1 is not an array

[Quanatee]

I hit a problem at this line:

// Overwrite regular content with feed config, so you can influence the collection processing with feed config $page->header()->content = array_merge($page->header()->content, $this->feed_config);

Which shows up this warning: E_WARNING - array_merge(): Argument #1 is not an array

Could I get some insight on what the issue might be?

This still happens to me on a fresh install.

@briankelleher I worked around this by not using the plugin at all. Made a template using twig. Works even better since I get to customize my own feeds now. This is a quickly watered down code that should work for stock grav. It will only reflect visible posts that are posted within the running week. Without that condition the feed will produce everything you have.

{% set collection = page.collection() %}
<?xml version="1.0" encoding="utf-8"?>
<rss xmlns:atom="http://www.w3.org/2005/Atom" version="2.0">
    <channel>
        <title>{{ site.title }}</title>
        <link>{{ page.url(true) }}</link>
        <description>{{ site.description }}</description>
        <language>{{ collection.params.lang }}</language>
        <atom:link href="{{ uri.url(true) }}" rel="self" type="application/rss+xml"/>
        {% for post in collection %}
        {% if post.visible %}
        {% if date(post.date) > date("-7days") %}
        <item>
            <title>{{ post.title }}</title>
            <link>{{ post.url(true) }}</link>
            <description>
                <![CDATA[{{ post.content | truncate(140) }}]]>
            </description>
            <category>{{ post.taxonomy.tag|join(",") }}</category>
            <guid>{{ post.url(true) }}</guid>
            <pubDate>{{ post.date|date("D, d M Y H:i:s O") }}</pubDate>
        </item>                                      

        {% endif %}
    {% endif %}
{% endfor %}
    </channel>

</rss>

@rymdluo I appreciate it, I guess I will go with a custom solution.

I am only able to replicate that error message by running on a page with

---
title: Blog
content:
---

# My blog

(no collection defined).

What is your page header content? And how are you calling the feed? On the collection page, right? Like, http://mysite.com/blog.rss, where Blog is a page that defines a collection.
