My solution

1 make a backup – files and mysql

2 delete all files

3 delete mysql

4 reinstall wordpress and plugins in same versions of the backup

5 restore mysql

6 restore them files

7 restores themes/uploads

With this i have the last version of wordpress same content and no errors

i think its a “virus/hack” cause all sites in my host have the same problem, and i didnt uptdate wordpress in last week
