We are running Moodle 2.6
We are trying to integrate an LTI and accept grades from the LTI provider. Currently the grades are not being pushed to our Moodle gradebook. The LTI is set up to accept grades from tool Always. When a student takes an LTi quiz our server logs indicate the following:
Aug 15 10:33:21 arp4 httpd: test.test.gov 22.214.171.124 - - [15/Aug/2014:10:33:20 -0500] "POST /mod/lti/service.php HTTP/1.1" 404 12421 "-" "OAuth gem v0.4.7"
Also when I enable debugging and take the quiz as a student, receive this error:
Undefined offset: 1 in /usr/docroot/moodle/mod/lti/lib.php on line 471
Any ideas as to how I begin to track down this issue? The providers content is on an http while our moodle is set to https. Could this have a connection?
