Thank you again.
It was the location code.
Fixed now.

Reasons for a payment module to not show during checkout (none of them are specific to Square):
- A Payment Zone restriction has been set, and the address being used for checkout isn't in that zone. Set Payment Zone to --none-- in the module, to remove all restrictions
- Another plugin is interfering with the default checkout process, and a billing country/state haven't been specified.
- Strange/unusual alterations to checkout templates. This is rare, but does happen, depending on who customizes them.


You haven't listed:
- what template is in use
- all the plugins on the site
- which other payment modules are enabled
