We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
There is no content.js file in Composr CMS as the error would indicate. This leaves me to believe the error is being triggered by a browser extension, particularly upon discussing this with Master Rat, it might be Shopify.
I am closing this as this issue is beyond Composr CMS.
