Hello,

We are having a very frustrating problem where our navigation menu for our wordpress site (reauthoringteaching.com) keeps disappearing and we have to manually add all the items back again.

This has happened twice over the last 4 days. We can't afford for it to keep happening as it takes AGES to add the menu back.

We think we must have a plugin conflict, but given that the menu disappears at random times, we don't know how to test for which plugin may be causing the error.

We have a lot of plugins and it would take weeks to disable them one by one for a week to see if the menu stays put.

Do you have any magic tricks which may assist us in identifying the troublesome culprit?

PLEASE HELP!
