This plugin shares code with the new mod_turnitintool2 plugin which must be installed at the same time.

This version has a number of major benefits:
  • Fully supported by Turnitin for all issues that occur.
  • Uses a new improved API to connect to Turnitin.
  • Better support for the rest of Turnitin's product range (Grademark, Writecycle etc)
  • Works with the new Moodle block developed by Turnitin

    Hi John,

    I have a problem where only one of my courses of 12 is currently showing TurnItIn document submission values, and the "Refresh Submissions" and "Launch Peermark Manager" settings when editing the case discussion forum directly.

    Is there a reason why this would only be enabled for one course? I have spent the day try to debug but cannot spot any errors or patterns.

    Hi all,

    This addition to the Assignment should work great for us, but during my testing I can't seem to see a way of getting Originality scores to display as in the screenshots for the plugin. Am I missing something?

    Hi All,
    We have installed latest version but when we are using we recieved a error that "$.colorbox is not a function".
    Even though we tried to require this but its not accepting the js file. Can anyone help us to resolve this case.

    Hi John Paul, are the files being sent to Turnitin? Check your db, cron output and API logs.

    Hi Shiva, we have seen this issue with a few other people. Is this on all modals you are seeing this?

    Hi John McGettrick,
    Yes, our users are unable to accept the license key while trying to access the turitin assignment with message "To submit a file to Turnitin you must first accept our EULA. Choosing to not accept our EULA will submit your file to Moodle only".

    Hi Shiva, is the EULA with the modal showing at all? Are you using a custom theme and something is interfering with colorbox? Can you contact product support so we can get some more information please?

    Please update line 554 of /turnitin/lib.php so that it references the correctly titled javascript file located under /turnitintooltwo/jquery (in version 2018102601) - without which new users are not able to accept Turnitin's EULA. Line 554 should now reference turnitintooltwo-2018102601.min.js NOT turnitintooltwo-2018082301.min.js.

    It would be ideal if you refresh line 554 of/turnitin/lib.php so it references the accurately titled javascript document situated under/turnitintooltwo/jquery (in rendition 2018102601) - without which new clients are not ready to acknowledge Turnitin's EULA. Line 554 should now reference turnitintooltwo-2018102601.min.js NOT turnitintooltwo-2018082301.min.js.
    I have use GBWhatsapp For IOS Version. This app is very nice.
