Thread:Extension talk:MsCalendar/no wiki markup parsed after usage line/reply (2)

This bug was almost surely because you copy-pasted the wikitext in the documentation, which said:  If you look closely, the opening tag is "mscalendar", while the closing tag is "calendar", so the "mscalendar" tag never got properly closed, and all wikitext after it was considered part of it. Close the tag properly and the bug is gone. I've fixed the documentation to prevent further confusion.
