Hi
I got the same but for profiles I manage.
It's Wikitree's way of calling attention to tools that report error messages about problems with profiles, and included an invite to help cleanup profiles tree wide, so it's not directed at you or your efforts as an individual.
On this occasion it was for profiles added by gedcom import with problems, I had about 88.
I've fixed some and have more to fix.
It's easy to make mistakes on Wikitree, I've made a lot. Wikitree's complicated, help is often unclear and one click or typo can generate an error report.
Somewhere on Wikitree I've seen the message "Don't be afraid to make mistakes"
The message we all got wasn't to say we made mistakes, but telling us where to find a report about profiles we manage with problems, some of my profiles I adopted complete with errors I didn't spot.
Your list of errors might be empty, otherwise check the profiles listed and try and spot what's wrong, if not ask what's wrong on G2G.
I've never seen this stated on Wikitree, but it operates on the principles of continuous quality improvement, and that requires identifying mistakes and fixing them.
Wikitree is a steep learning curve, 6 or so years in I'm still learning, fixing mistakes and improving profiles with info I didn't have earlier (and still making mistakes). Also Wikitree changes it's policies from time to time resulting in error reports on profiles that were compliant when created.
