I am getting an error message in Chrome that says 'Refused to set unsafe header "Connection"' on several websites that we have deployed to their live server. we do not see any problems with this during local development or when the site is on a staging server behind our firewall.
when we receive this message it seems to be when we start a new browsing session, and when we log into the cms we notice that complextablefields do not load correctly, and it looks like they are missing their styling. (this is when we receive the error). if we refresh the browser the error message goes away and everything seems to run fine until the next session.
i saw some other posts saying to check for extra carriage returns after the closing ?> php tag, but i'm using short tags and dont have the closing php tag just for this reason.
also, this only happens at work. if i log in from home or on another network i don't see the error message.
any ideas what could be causing this?
