Error in whitelisting addresses?

If you get an error thrown when trying to add more addresses, then you probably didnt check your addresses before adding them.

How do I check my Addresses?

Basically all addresses should be valid Addresses, the best way to do this, is with an editor:
We will use these following tools to check our addresses:

1. Load the Addresses seperated by "NewLine" into a new File

2. Delete the duplicates:

3. Use the online tool to seperate the addresses by ","

4. Now it should work. If you still got errors, make sure to split up your addresses in smaller batches and check for the invalid address.
