I've added WoW 8.x (BfA) compatibility, but can't test it since I don't have beta access, and don't expect to get a beta invite since my account doesn't have an active subscription.
If you do have beta access, and are the author or user of an addon that uses LibResInfo, grab the latest version from GitHub (
https://github.com/phanx-wow/LibResInfo) and let me know whether it's working.
If it's not working, please open a ticket on GitHub and/or post in this thread with the
error message. If there's no error message, run "
/lri 3" to enable additional debugging (slash command only present with standalone version) and
copy or screenshot the resulting messages. If you use ChatFrame3 for something already, use e.g. "
/lri ChatFrame7" to move debugging to a different chat frame.
