When attempting to use the UPS Shipping Extension for Exp-resso store, the install runs fine, but when attempting to add anything to the cart on the front-end we get the message:
A PHP Error was encountered
Message: call_user_func_array() expects parameter 1 to be a valid callback, class 'Store_ups_ext' does not have a method 'store_order_shipping_methods'
Line Number: 262
I have attempted to uninstall and reinstall the UPS extension, the EE installation was newly installed prior to adding the UPS Extension.
We are using the following:
- EE 2.9.2
- Store 2.5.0
- UPS Extension 1.1.0
