Is caching just turned off? I\'m even more confused as to why directly accessing the png doesn\'t have this delay issue. I\'m guessing php is caching images that are accessed, but the server isn\'t?
Notifications containing quotations leading to the wrong url is fixed. We used the clean function that we use for the DB when passing it to the pusher. I just changed it to only use it for the DB.
I refreshed this page while doing testing on push notifications and it spammed the thread. The other post pages don\'t seem to have this issue so I\'m going to look into that.
