svn error

1. The file system format is expected to be between "1" and "4"; the format "6"
    1 is found. It is said that it is because of the problem of the client version, but the same is true when I test it on the server; Open the current project /db/format file in the SVN server warehouse and change 6 to 4 to
    2, or restart the service.
Second , the svn icon does not display the problem: http://jingyan.baidu.com/article/36d6ed1f4c96901bce488354.html
