Warning: Missing argument 3 for BP_Course_Offline

Thanks Alex. This kind of makes sense, but I don't entirely understand your explanation. We are using a child template to customize, but if I copy it from the same place to the same location am I not duplicating the same thing, I don't quite understand? Can you give me the  directory path I am copying curriculum.php from and then the directory path I am pasting to; therefore replacing the the incorrect curriculum php file. Thanks for your help and apologies if I didn't quite understand.  

Hi Alex, Our IT developer is away today and we have an urgent issue and I'm hoping you can please help progress this thread. We have upgraded our test site, but have received the above warning message. Before we release the upgrades to our live site, I'd like to have the fix in place. The reason for the urgency to upgrade our live site is that our students are experiencing significant issues with Large Text quiz submissions. Students are completing 3 hour practice exams, but their responses are not being saved. When they click submit, we look in the Quiz Submissions queue, and the marked answers for the submission are blank. We had a similar issue last September/October. Please see this thread: https://wplms.io/support/forums/topic/large-text-question-quizzes-not-submitting-answers/ In the end, Mr Vibe looked at our live site and upgraded the Vibe plug-ins, which seemed to resolve the issue. In the meantime, we are recommending students use the latest version of Chrome and to save their responses into a Word document. Thank you for your assistance with this.   Test site: www.keqtest.com Live site: www.knowledgequity.com.au Username: kain Password: SDDvsu28&(1   Regards, Russell

Hi Alex, I'm sorry, but it's not something you can replicate every time. We have > 1000 students on the site, and about 20% of submissions are coming through blank. As per the other forum thread that I linked to, I have tried to replicate the issue using different devices, browsers, internet connections, and I have only been able to generate the error about 2 times out of 50 attempts. We recommend our students use the latest version of Chrome and have wired internet connection, but the number of issues we're experiencing is too great to just be 'user error'. If you're able to assist with the resolution of the 'Warning' message we are receiving (Missing argument 3 for BP_Course_Offline), then we can at least upgrade our live site to the latest Vibe versions and see if that helps resolve the issue with the Large Text submissions. Thanks for your continued assistance here. Regards, Russell
