If your Web Dispatcher configurations are completed and SICF transaction activations are OK but you still getting “HTTP 500 Internal Server Error” then give a chance to following check to eliminate this situation…

Check you HTTPS page and assume that it looks like show below ;

Check you SAP Web Dispatcher profile ;

Find the parameter : wdisp/ssl_encrypt value

Change the value to “0″

wdisp/ssl_encrypt = 0

Restart the SAP Web Dispatcher and check your HTTPS

I hope it’s also works for you…
