Hey David - we've been having trouble updating the auth_saml2 plugin..
When submitting the upload form it sits there and eventually gives the "Something seems to be wrong with the Internet." moodle error.
Steps to reproduce:
Open this page:
Upload the zip from this link:
Save the form and it dies
any chance you could take a look to see what's going on there in the backend at some point so we can update the plugin?
