Error: Error building site: failed to process shortcode:

[avvial]

Anyone able to help with this error?

1. I installed Go and Hugo (binary) and checked the version: \projects>hugo version hugo v0.111.2-4164f8fef9d71f50ef3962897e319ab6219a1dad+extended windows/amd64 BuildDate=2023-03-05T12:32:20Z VendorInfo=gohugoio

2. Created a new site for testing \projects>hugo new site docs Congratulations! Your new Hugo site is created in C:\Users\Anthony\Documents\projects\docs.

3. Downloaded the ace-documentation from git \projects\docs>cd themes \projects\docs\themes>git clone https://github.com/vantagedesign/ace-documentation Cloning into 'ace-documentation'... ... Resolving deltas: 100% (268/268), done.

4. Copied the example folders \projects\docs\themes\ace-documentation\exampleSite\content to \projects\docs\content \projects\docs\themes\ace-documentation\exampleSite\resources to \projects\docs\resources

5. Update the configuration file \projects\docs\config.toml now contains: baseURL = 'Users/Anthony/Documents/projects/docs' languageCode = 'en-us' title = 'My New Hugo Site' theme = "ace-documentation"

6. Ran Hugo (Note: full path shortened for clarity) Error: Error building site: C: ... \projects\docs\content\shortcodes\doublecode.md:23:1": failed to render shortcode "code": failed to process shortcode: "C: ... \projects\docs\themes\ace-documentation\layouts\shortcodes\code.html:23:67": execute of template failed: template: shortcodes/code.html:23:67: executing "shortcodes/code.html" at : error calling markdownify: "C: ... \projects\docs\content_index.md:3:1": failed to extract shortcode: unclosed shortcode "doublecode"

I have tried other installations, in other project locations, with the same resulting error.

What have I missed? Any help appreciated.
