Where is the web page wizard

web page does not appear in wizard list. has it been discontinued?

Hello,

see LibreOffice 5.4 - Release Notes - 14.2, which states:

The Web wizard (which exports a set of documents as html with an index and some styles from the last century) has been removed. Note that this doesn’t affect the HTML export. tdf#99967 (Samuel Mehrbrodt, CIB)

Hope that answers your question
