thanks for the reply
this is now Solved
i couldn’t view the invoices e.g
mydomain/wpi_invoice/inv-50549/
however it was an error on my part – i created a blog layout in themer and the location settings in the themer needed amending
i can now view correctly
just to add – i tried setting rules on each themer layot so that it excluded the invoice pages but that didn’t work,
i can only see invoices when beaver themer is deactivated
