All Products disappear from Shop Page

Hello- all the products in our Shop Page keep disappearing, but reappear once I go into the backend and manually update the page (by literally clicking update). It seems to be on a schedule. At first it was hourly, so I deactivated the Facebook Woocommerce plugin because I noticed it coincided with the Facebook “heartbeat”. That seemed to help, as it wasn’t disappearing hourly anymore, however, all the products are still disappearing randomly- I’m still trying to figure out the timing pattern for when the products disappear. I understand that I will need to deactivate and test all the plugins, but being that we are not on an hourly schedule of disappearing and have 30 plugins installed, I’m afraid this will literally take me months to figure out- while losing valuable customers in the process. Do you have any suggestions or has anyone else reported the same issue?
