Thank you for the response. Based on the logs, the user was actually able to login and upon logging in, this error message appears. I've set the debugging to developer and got this:
Debug info: ERROR: invalid input syntax for type bigint: "courseindexpage"
SELECT * FROM mdl_course WHERE id = $1
[array (
0 => 'courseindexpage',
)]
Error code: dmlreadexception
