[ISSUE] BMSworld login error ‘SOLUTION | Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress’

Ahh the dreaded

“Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress”

I think I’ve finally solved this – turns out that is you 303 redirect things to make other things more secure, you also need to set a cookie on your browser making sure that HTTPS is specified as the cookie domain, not HTTP thus causing a cookie security origin mismatch…

At times like this, I wish I would just slow down a bit 😉
