What is causing this Error?

MICROS is set to reject unsigned interfaces and is refusing to save the settings.

How do I resolve this Error?

You will need to allow unsigned interfaces to finish setting up the Shift4 Interface in e7.

Perform the following:

1. Log into e7 with a MICROS Manager PIN. 
2. Once logged in, locate the Configurator button within the e7 operations screen. (Screen layout is customizable and the button location can vary.)
   • Enter your MICROS Manager username and password after this selection
3. Once the e7 Configurator is open, in the top-left corner is a file system drop-down menu, locate the option of Restaurants in the drop-down list.
4. Select the Security option.
5. Enable the option of “allow unsigned interfaces”.
6. Press Save () to save the configuration.
