Hello. The error occurred in a MySQL database. Certain sections cannot be deleted, because under them there are no buttons "delete" and "change". Tried to move the website to a new host with a clean WordPress, but while importing the database re-appeared this problem.
Question: is it possible to delete the data of the rubric by making changes to the database itself via phpMyAdmin? If possible, write which table in the database is responsible for heading and how to find and remove.
