Hi, I’ve just hit the same problem .. but it was affecting some people all of the time and some people some of the time. I guess this was some sort of caching issue, however whereas turning off minification seemed to help, the issue quickly returned. I’ve now set the CloudFlare account in “development mode”, which bypasses the proxy, this seems to solve it (for now at least). I tried setting development mode previously and purging the cache, but it had no effect .. now it seems development mode AND disabling minification works. (which makes little sense to me)
This is a very odd problem and is something that’s going to make me think twice before I click the upgrade button again. If anyone has any more info on this it would be much appreciated.
(just to note; this is a new issue, nothing apart from updates has really changed in the last few months)
