Get the same thing and am getting quite annoyed with it. It's supposed to be caused by entering the wrong usernam/password etc but I have trippelchecked, it IS correct. So..... what's causing this?

 

Anyone?

I was having the same problems...

First internal server error.. turned out to be Curl wasn't installed on my hostgator account.

 

Then the invalid security errors..

 

Turned out to be I had it in sandbox with live api sigs and data...

 

Works now!

 

Thanks everyone..

Take it out of sandbox and put in live, I had the same issue.

I am in Live. I triple checked my credentials. Still get Security header is not valid. CURL is correct.
