Blizzard launcher and WoW files are both set to run as administrator. Despite this my Chat settings keep on activating “system” and sometimes even “channel” chat for my main view…
Could try /resetchat and then setting stuff up again.
didn’t work
Try disabling addons and seeing if your settings save. If they do then you have an addon overriding them. If they don’t then it’s possible your anti-virus software is preventing writing to the chat settings file.
