I updated the addon to the currently latest 1.5.2 version but by statistics just froze, it doesn't load... I've tried debuging it by disabling all the the similar addon that shows up in the same position but still doesn't load. One thing to mention - while it hasn't been a problem before - I'm on cloudflare and make use of the standart caching & optimization method (not rocket loader).
Interesting development; now the statistics show up again. The only thing I made differently is to flush cloudflare cache.
