Found this on the debug after site failed to load:

# JROOT/libraries/rokcommon/functions.php

LOADING_CONTAINER_CONFIG_FILE_FOR_S_FROM_S="container config file for %s from %s"
REGISTERING_LIBRARY_PATH_S_FOR_S="library path %s for %s"

There are no generic errors displaying on the file, however the console show a wad of mootools errors headed:

mootools-more-uncompressed.js?9aeb18d…:6114 Uncaught TypeError: Cannot read property 'retrieve' of null
Any ideas?

Hello Julie,

These issues do not really seem to be coming from K2.
It's either the RT template or an extension from RT (rokcommon).
