Is it possible to upgrade to a more current version of PHP? PHP 5.4 is really old: its last update was Sept 2015.

The normal flow is:
- Click green button
- it takes you to the Square site, asking for login if you're not already logged in. Presents an authorization prompt if not already authorized.
- returns you to your store admin
- If the "Access Token Needed" alert is still showing, press F5 to reload the admin page in your browser.

Is the directory you've been quoting (C:/Web Files/localuser/CHCG/Shop/) a local development PC? Or is it the live production server for your domain?
What browser/s are you doing this Admin / SquareLogin in?

Any logs generated by the module are stored with other error reports in the /logs/ folder as "myDebug-xxxxxxxx.log" filenames.
