Multiple stores - trouble moving from one to the other

Hi have recently created a new store and seller I.D to reflect a different product range. I have listed several items using the new seller I.D but have encountered this error message when trying to list items using the original account.
"An error occurred while compiling an eBay API request for template . Please check your Console output."
I’ve switched accounts in preferences, refreshed paypal and token options etc.
Any tips on what I need to do please.
Regards David

Is you template linked to an inventory item via its SKU? Does the inventory item include images?
