Some time ago I used to get an error after posting comments on my blog from certain computers. I thought it had resolved itself until someone else reported this behaviour.
Please see screenshot for an example of what I mean. I believe it must have something to do with validating the IP address, due to the first line of the error message and since it seems to be location specific.
I believe I'm using SK2 2.3rc1, but it happened with the previous version as well.
Is this fixable?
