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.
#2746 - Sometimes block loading results in a MySQL query error
Thanks. Also, is it weird that if a block causes an error, it loads up global_html_wrap again to display the error (and you then get two headers/pages in one)?
It happens when the session ID is numeric. PHP changes numeric array indices into integers, so we get it back with an integer and it breaks a query.
This is the chance of it happening:
