I blekko'd it. Blekko is shit.
I think there's a reason we don't tell people to "Blekko" it.
Right, doesn't happen with add-ons disabled. Time to update them all then...
Probably just one of them. If you can be bothered enable them all and disable them one by one.
Don't think I've worked out how to turn them all back on after turning them all off :$
More efficient to just enable one by one, until offender is found?
