A forum member reported that she was unable to access https://se23.life this morning on her iPad. In the logs there are lots of errors regarding “e.getRootNode is not a function”. I asked her to try in safe mode and when she did, the problem persisted (so I don’t think this problem relates to plugins or customisation)
The user agent is “Mozilla/5.0 (iPad; CPU OS 10_2 like Mac OS X) AppleWebKit/602.3.12 (KHTML, like Gecko) Version/10.0 Mobile/14C92 Safari/602.1”
Is it possible the version of Safari is the problem?
I note on the getRootNodebrowser compatibility matrix, it was only supported since version Safari version 10.1, and the user agent indicates version 10
Okay I’ve done some more digging in the Discourse code base.
I found one reference to getRootNode, and it was added six days ago by @j.jaffeux (no personal blame intended by my post). The file is vendor/assets/javascripts/jquery.js (note that you may need to click to expand in the github diff as it’s a large file)
I believe this change has inadvertently affected backward compatibility with older browsers that we might hope that Discourse would continue to support (the user in my case was using an iPad Mini 2 running iOS 10.2, which is by no means prehistoric)
