Found a Liquid block containing the excerpt separator "\n\n" #25
Description
In files where I use katex, I get the following error at compile time:
Warning: Excerpt modified in _posts/2019-07-18-encrypting-secrets-in-memory.md!
Found a Liquid block containing the excerpt separator "\n\n".
The block has been modified with the appropriate closing tag.
Feel free to define a custom excerpt or excerpt_separator in the document's front matter if the generated excerpt is unsatisfactory.
I'm not sure what it's referring to as I have the correct {% katexmm %} and {% endkatexmm %} tags at the start and end of the page.
