Not sure what happened, but this web site suddenly started showing an annoying “join our userbase” popup.
It appears to be due to an upgrade of the ‘Really Simple Share’ plugin that gives the Facebook Like, Google Plus +1 buttons etc.
The popup seems to be from an organisation galled ReadyGraph, but I don’t want it, and the the ‘Really Simple Share’ settings were not accessible, even from my administrator log-in. I have disabled the plugin for now…..
