Thank you!
So I can't just write a line to delete all peoperty keys, right?
Yeah that's right, there is no alternative option right now:)
Documentation only support enterprise edition...
and I don't know which part of the folder can be deleted...
Is there a documentation support Community version?
Delete the neo4j folder in the databases folder and it should be good but you will have to recreate a database after.
I delete the noe4j database...and I couldn't create it back...
How to create a database in community version?
Did you shutdown the server before to delete the folder and did you restart it after?
You should open another topic for this problem.
Thank you!
Yes, I did shutdown the server before I delete the neo4j folder and restart it.
But it turns out to be the picture I sent. So I delete the whole folder and download a new community version 
Now it's ok.
I will open another topic when I have to create a database after.
