I updated SimpleSAML_php authentication from 8.x-3.0 to 8.x-3.2.
Since then, whenever I click on the SSO login button, I get this error.
Exception: Could not resolve 'saml:SP': no class named 'sspmod_saml_Auth\Source_SP' or 'SimpleSAML\Module\saml\Auth\Source\SP'. in SimpleSAML\Module::resolveClass() (line 194 of /var/www/html/simplesamlphp/lib/SimpleSAML/Module.php).
I searched, but I couldn't find any information on it.
Everything is already set up (configurations, entityID in authsourse.php), but I still get this error.
