"There were errors loading the rules"
I'm trying to get this message to go a way. The rules still seem to be functioning even with this message however.
I was trying to get a limiter setup and I was adding and deleting floating rules as well as limiters when this showed up. Pfsense version is 2.0.3.
Click the error in the notification bar, or click "acknowledge all" and it will go away. Go to Status > Filter Reload, click the button to have it to a filter reload. If there are no errors, then it's all OK now.
