Using latest version 2.1.6 of Magento2. Payment methods are enabled in admin but not showing on our checkout page. They are showing fine when we manually process an order from the sales > orders area of Magento dashboard. Shipping methods show fine. All they obvious settings are in place and cache cleared etc. Any ideas where to start on establishing why this issue occurs?
First line of system.log file entry I think is related is below:
[2017-05-11 13:06:07] main.INFO: Item Magento_Backend::system_currency was removed  
But the currency is set as it should be in Magento settings.
