Every time I open safari I see this message "An error occurred while attempting to initialize the value for cmi.core.lesson_status to incomplete" if I click OK it just keeps reopening. I can't open safari preferences to reset the cache, etc... because of this message and reseting my computer did not solve the issue either. The only way to stop this is by force quitting. The core.lesson it is referring to is the from the site I had open right when this started occuring, this is a trusted website so I do not believe there was a virus there causing this. Any advice would be much appreciated. Thanks!
