when i tried to check to see if i could perhaps set it to uk only and that would allow it to suddenly work. no joy, just happened to spot this message so i goes to insert the missing file and it is indeed missing, the error is still there and the settings options dissapeared from the admin panel.
deleting square_handler.php gets those settings back in the admin panel?

i havent tried implementing the SCA patch as above as developers i hired for upgrade left my site in a sorry state and ive had to let them go
When loading the payment modules screen, is the only issue logged in the logs file related to this module or are there other issues logged as well? Is english the only language used by the catalog and/or admin side?

What files are in includes/modules/payment? From what version was your site upgraded? What php version is currently being seen by your site (info is expected on the screen at admin screen version link at upper right.)
