A client’s wordpress site uses Custompress. I haven’t done any updates since 2015, and am now upgrading the system from the version stated in title. I have updated CP from 18.104.22.168 to 1.3.59 and everything works fine.
I have spent the last day trying to resolve why one of my custompress custom content type taxonomies are disappearing.
I have updated all plugins and the taxonomies remain, but when I upgrade WP from 4.4.7 to 4.7.2 they disappear.
WordPress then wants to do a database update. After this, the taxonomies are gone.
What’s really weird is that I can step back the file system to 4.4.7 and then WP wants to do a database upgrade, and the taxonomies appear again?
So they’re obviously not been overwritten during the upgrade process from 4.4.7 to 4.7.2
Any help would be greatly appreciated!
