We have this on our site and have used it for 5+ years. It has worked consistently within our Posts in the magazine and readers value the Save funtion because they can do the crossword in multiple sessions. When we email for support we have always received courteous and helpful responses and the issues have been resolved. These comments remain true, even though our Wordpress version 5.8.1 has not officially been tested with Crossword Compiler.

There is no real admin the addon. While we love the software and use it for our little newspaper we HATE the fact that they want to charge you $1000 to remove the link to their website.
