Yesterday evening around 8pm subeta time, I purchased CSW. Everything appeared to work as normal, the site saying upon approval I would get my CSW. One of your 504 warnings showed up shortly thereafter. When it did not show up after an hour or so, I checked my paypal account and nothing showed. I assumed that my purchase was glitched by the 504 thing, so tried again. Still nothing here or on my paypal account. Not willing to try purchasing again in case the system is just delayed in processing CSW purchases.
