Hi all. Wondering if anyone has experienced problems upgrading from 2019.1 to 2019.2? I had the SCA site up and running (no theming yet but functionality all working) in 2019.1. But we now want to implement the segment/catalog functionality in 2019.2. So I downloaded and installed the 2019.2 bundle, reset the touch points, image files etc. And now I've lost functionality of the working site as follows: --> Unhandled error on the homepage viewed in Console: Uncaught SyntaxError: Unexpected token '<' within file shopping.environment.shortcache.ssp --> Unable to login. No page renders (blank screen) and there is a console error (in addition to the one above)

Uncaught TypeError: Cannot read property 'locale' of undefined
    at Array.<anonymous> (checkout.ssp?fragment=login-register&is=login&login=T:51)
    at Deferred.resolve (checkout.ssp?fragment=login-register&is=login&login=T:51)
    at XMLHttpRequest.http.onreadystatechange (checkout.ssp?fragment=login-register&is=login&login=T:51)

I will keep investigating and potentially submit a case to NS but just thought I'd throw it out there in case anything obvious jumps out at anyone. Cheers
