Yes, attach a source file.
dokuwiki\data\pages\playground\http_status_code.txt.
I am using headline and unordered lists.
Today try again.
When saving, it is error many times.
HTTP response code is 500.
Data file is created normally, but dokuwiki\data\index\page.idx is no updated.
And, page.idx is not updated at all, other data and other namespace.
Indexer problem???
