I just don't know where to start. A handful of users, since last night, are having to log in every time they visit our forum with safari on their iphones. I made some changes to our CDN last night but nothing that should affect cookies.. Specifically I disabled the zone referrer functionality (made it possible to only allow certain domains to access the CDN) because it was giving us some problems (google couldn't index our attachments stored on the cdn etc). ANYWAY, Steps tried: - reboot/ reset phone - cleared history and website data - verified that safari is allowing cookies on sites i visit - "stay logged in" is checked And still these users have to log in every time. Anyone have an idea how to troubleshoot? I'm unable to duplicate this issue as are my forum admins. Is there any way to see what cookie data is stored on an iphone? Thanks Edit: this isn't a xenforo issue, so feel free to move to off-topic or something.... sorry.
