@droftarts et al
I have worked out a work around for this - it should prevent future code blocks from having the issue - but will not go back and replace existing code in existing posts.
I think this is limited to some keywords within the quotes as well as the quotes them selves and is a bug with the SQL and PHP autodetection highlighter line numbers are set:
1d132169-94b1-47eb-be18-66b8ba49bc55-image.png
Turn of line number for SQL and PHP:
96db78ab-9572-4f5d-b61d-828752ee2171-image.png
so since we don't post SQL/PHP on this forum then turning off the line numbering wont impact anyone .
If the autodetection detects your post code as SQL/PHP then force it to be JSON or something
"special words & order: map, create "
arbitrary text
.
