Any ideas why this would keep popping up? It appears when accessing or editing products - most frequently after saving changes to a product then trying to access another (but also during other actions). It doesn't crop up consistenty, but does crop up frequently.

Hi,

HikaShop does not touch or interact with the Joomla session.
So we don't know why you have these messages and I don't think that there is something in the HikaShop product edition code (or in the backend) which can be responsible for that.
More than HikaShop ; your joomla website also have (system) plugins.

Regards,
