I updated a MODx website from 2.3.1 to 2.4.0 which included Tagger v1.5.0. Everything in the upgrade seemed to work fine. Tagger seemed to run fine also.
However when I try to update Tagger in the package manager from v1.5.0 to 1.7.0 it erased the tag groups. Then won't let me add any new groups at all.
I have restored the site and upgraded twice, just to be sure. Same problem both times.
Any ideas what might be happening or how I can fix it?
Also happens when upgrading from 1.50 to 1.8.0, on MODx versions 2.4.0 or 2.5.2.
Has anyone else seen this?
