No matter what is it that I edit. The error pops up, but usually the message will change. However as of late editing opening posts is just unavailable for me and refuses to work.
I can however still edit posts that aren’t the original topic But the error message still stands.
I’ve had this problem as well. Not much to add other than that you’re not alone
I’m on Chrome and Windows 7 if that matters.
I haven’t had any issues. A new version of Discourse is out but I’ve been waiting until the campaign is over before I upgrade.
