Re: Activation link show me errors
DJPaul-
As I posted above, I’m beginning to wonder if more is going on with some installations as we’re seeing more of this error type. I’m not saying that it is because of your plugin though! 
With WordPress installs, this “Cannot modify header” error almost always indicates extra stuff before an opening php or closing php tag. It is all too easy for someone to open up a file and accidentally enter extra “stuff” and not even realize it.
But there are of course other causes of this error. It will be interesting to see what the source of this error turns out to be.
