The same happens to me whenever I add some custom header tag in the page frontmatter like

star_ratings:
    disabled: true

[muflone]

In the meantime I've made a workaround:

    if (is_array($replacements))
        $text = preg_replace(array_keys($replacements), $replacements, $text);

[magnetik]

Maybe if you do a pull request it will be merged. Thanks for sharing your workaround anyway !

The same happened to me, and I applied the workaround by @muflone to "classes/Toc.php" line 440.
Now it works well. Thanks and hope this fix to be merged!

Thanks guys I have merged it. Will fix some other bugs before next release.
