We are suddenly experiencing a problem on our site where we cannot add any product on our website to the cart. This just started happening within the past 48 hours, but nothing has changed. The odd part, is that no error is generated, no log is generated, It simply hands after clicking add to cart, and it just spins. No response after that (we've let it sit for 1hr, to no avail).
We've tried clearing out the /pub/static, /var/cache sessions cache di page_cache view_preprocessed, and the problem persists. No errors show up and I cannot seem to find a rhyme or reason as to the cause.
Is there some way to turn on debugging after I click a button (but nothing else happens) ?
