ok, reviving this because it never got fixed, which makes the archive look just broken. that tester site doesn’t support the query unfortunately.
again here’s what i’m using
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^([^.]+)$ $1.html [NC,L]
/community
../community.html
and
/community/
/.html
i’m hoping to simply have an overriding condition that the root is not treated by the condition.
