Q. I receive the warning universalvariable is undefined or Missing nToklo API key. Requires variable assignment: _ntoklo_key.

A. Your universal_variable object and _ntoklo_key must be defined before the nToklo Javascript tag. Please refer documentation on nToklo Javascript tag.

Q. I have installed the nToklo plugin, and placed a Recommendation widget. Why don't I see any recommendations?

A. There must be enough user activity in order for nToklo to compute recommended products. Once there is enough user activity you should begin to see recommendations. New nToklo customers will also have to wait 24 hours before recommendations and charts are computed.
