I have had a website for over 10 years.
Sometimes you just build up a whole heap of clutter.
Sometimes you need to back it all up and start fresh.
If you have arrived looking for some of the old content, I’m sorry it is not available right now.
The Glossary plugin is something I haven’t tested or maintained for a long time and there are some very good options on the WordPress.org Plugin Directory.
The Quantcast Quantifier is also a plugin I haven’t worked on for a long time.
A quick search on WordPress.org Plugin Directory shows that maybe it is worth reviewing this plugin.
