Seeing the same thing with adblock. When selecting valid zones I receive this error:
When I try to save and apply, I receive this message:
If I add the zones via the config and restart, the corresponding Firewall Traffic Rules are created successfully.
I’m running OpenWrt 24.10-SNAPSHOT r27986+351-fc236f3b3c / LuCI openwrt-24.10 branch 25.013.61065~e7949bd – built today.
