Error rendering template

[Wonko52]

Fresh installation: when calling up the plug-in page, the error appears:
An exception has been thrown during the rendering of a template ("Warning: Array to string conversion").

The solution was:
Line 171 in var/plugins/DemoBundle/Resources/views/index.html.twig

{{ value }}
replace with
{{ value is iterable ? value|join(', ') : value }}
