When I tried to login to Paypal, for the first time I encountered internal server error (Error code 500). I was surprised by this error as it was least expected on a site like Paypal !!
However, it did not seem to be a problem for a long time. I encountered the error after I had keyed in my login credentials. I just refreshed the page and I was able to log in. Guess it was a temporary glitch from Paypal’s side, but then too a 500 Error on Paypal is quite surprising.
