I'm having some issues using V1 and V2 API's for some calls.
For V2 I'm getting errors like this
Procedure 'customerCustomerList' not present
Basically it was working until I renamed wsdl.xml and wsi.xml in shop/app/code/core/mage/customer/etc to wsdl2.xml and wsi2.xml and replaced them with slightly modified copies. The I deleted the modified copies and changed the two originals back to their original names.
Now I'm having all sorts of dramas.
I've tried clearing the cache and restarting the server.
