Asunto: Re: Empty blank page on some functions in Apache Stratos 

Hi Iago, 

This might be a problem with the identity management features installed. 
Please report this in JIRA: 

https://issues.apache.org/jira/browse/STRATOS 

Thanks

Hi, I'm new with Apache Stratos and I've downloaded the 4.1.5 version. On the 
admin panel I have some problems. I want to add SSO to my Apache Stratos (I 
have created an IDP and SP instance of OpenAM and I have the SSO working) but 
when I click on "SAML SSO > Register New Service Provider" I get an empty blank 
page :/ 

Also, If I go to "Identity Providers" and I try to add one new I get an empty 
blank page again BUT in "Service Providers" I can add without problems. 

Moreover, on "SAML SSO" if I click "Register New Service Provider" I get again 
an empty blank page. 

Why I have this issues? 

Thanks and regards. 



UPDATE 1: 



Looking on the terminal I've seen this error:
