I installed simplesamlphp to set up SSO configuration towards an ADFS server. But I have issues when I am trying to convert their metadata.

I can successfully log in to the initial installation welcome page, as well as other links such as authentication and federation tab, test the configuration etc.

But I get blank pages, when I click the "Configuration" tab, "Show Metadata" in Federation tab, or when I go to metadata converter page and click on "Parse". Basically I am guessing there is a redirection error, somewhere in the configuration code, but I couldn't find it in the internet.

I see below errors in the logs.

I found my own solution.

The reason was the missing modules for php.

After running below commands, everyting works.

sudo apt-get install php7.0-mbstring
sudo apt-get install php7.0-xml
sudo apt-get install php7.0-curl
