Hi, i found problem.
I try:
1.Disable all plugins, than activate 1 by 1. No result.
2.Reinstall woocomerce, try another versiom, downgrade, upgrade. No result.
3.Reinstall same versiom WordPress, downgrade to other version. No result.
4.Connect to PHPMYADMIN, go to table wp_term_taxonomy, delete latest posts about 200. Works well.
