Liquid Exception: Can't convert Hash into String. in /_layouts/default.html

Hi Team,

When trying to activate SEO plugin (adding {% seo %} to head section) I get the following error. This was not me who built the actual site on Jekyll and it is hard to trace the reason without Jekyll knowledge. Can you help identify the reason?

head.html is located in the _includes folder and is included into the default.html as {% include head.html %}

It was advised in the same topics to run jekyll build --trace for details. Here what I get:

Configuration file: F:/mywebsite/mywebsite-web/_config.yml
Source: F:/mywebsite/mywebsite-web
Destination: F:/mywebsite/mywebsite-web/_site

Hello @rndwork
Just in case you missed the suggestion at GitHub discussions, the error seems to be due to the logo setting in your config file.
jekyll-seo-tag expects it to be a string value instead of a mapping.

Therefore,

logo: mylogo.png

is acceptable but not

logo:
  src: mylogo.png
  width: 100px

Yes, thanks! I’ve already solved this issue.
