oscommerce derivative debug ups locator - nexi payment

Job ID: 32969957

Budget: €30 – €250 EUR

the module existed and worked until june 2021, then ups changed the system and now needs to be reprogrammed on similar oscommerce shop. The previous version of UPS locator showed two data to the user, in the left part of the screen the list of Access Points providing the service and, in the remaining part of the screen, the map indicating the Access Points themselves.
The customer selected the one of his interest and the name with the relative address was reported on the site.
Another problem is the Nexi payment module closes the order before actual payment, can you help me?
