Turnitin plagiarism plugin

Sounds like the php extension mbstring is missing on your web server. You should ask your sys admins to add it. (It's in the list of server recommendations in the admin notifications too.)

Hello,
We are currently in the process of updating our Moodle instance and all of its plugins to 3.2 and have run into an issue with the turnitin plagiarism plugin
in assignment editing pages. We recognise that the latest turnitin plugin is technically made for 3.1 but were hoping it would function okay with 3.2.
This error occurs only sometimes for editing assignment pages in certain courses and have yet to work out what separates one course working from one
that doesn't.
Here is the message we receive below:
Exception - Call to undefined function mb_strlen()

Are you able to shed any light on the situation?
Thank you for your time,

Hi Iñigo, it shouldn't affect the functionality but you will end up with a lot of notices like that if the debugging level is high. We are looking to rectify this for compatibility with Moodle 3.2.

Hi,
We're using this plugin (2.6+ 2016091401) on Moodle 3.1.2 and it throws this message to the admin:
The following plugins in your system are using Events 1 API deprecated handlers: 'plagiarism_turnitin'. Please, update them to use Events 2 API. See https://docs.moodle.org/dev/Event_2#Event_dispatching_and_observers.
I don't know if it make some trouble, but just in case.

Hey Corey, it is strange that this is affecting only students. Can you contact product support and we'll get some details off you?

Hey John it's build Turnitin Assignment 2.6+ 2016030101 . It happens continuously for all students, but not the teachers.

Hi Corey, what plugin version are you using? Is it happening consistently?

We are having issues with Moodle 3.1 timing out student attempts to access their feedback from the oline grader tool. Any thoughts as to what is causing this error? Teachers can still grade and access their feedback, but students cannot. It is not a permission issue.

Hi,
Do you have an estimate about when this plugin will be available to Moodle 3.1?
Regards
Oswaldo Rojas

A suggestion for future development is "smart filtering".
Is it possible that the Turnitin options are only available if appropriate submission types are used (i.e. File submissions) . This would prevent any confusion over expectation that Turnitin could check other submission types (e.g. text, video, mahara)
Thanks.

Hi John.. I already installed turnitin and mod plugin on my moodle, but i've got problems when i try to enter the password on turnitin shared key. I already put the right password that the administrator gave. Could you please help me?

Hi RabNawaz, I've just tried this out on a local install and it worked fine. Is there more information in your server logs or just the checksum exception?

Hi,
I am installing the plagiarism_turnitin on 2.6+ moodle, it gives an error the following error. Please help
"Oops! It did it again
Moodle deployment utility had a trouble with your request. See the docs page and the debugging information for more details.

Hi Maria,
You are correct, thanks for pointing it out. Small typing error on our part. we'll get it changed.

Hi,
Maybe I have found a mistake on version 3.0, component "plagiarism_turnitin", string "pp_digital_receipt_message". There you can read "from from", twice. Is that correct?
Thank you,
