Hi Nani

I suppose you use LSOAE 604 SP14.

We had the same problem with this version.

Solution for us is using SP13.

Hi Andrey,

Just like what you sail I reinstalled  LSOAE 604 SP13, the error was fixed.

Thank you and have a good day!

Thank you for posting this solution.

We ran into similar issue with LSOAE 604 SP14. Following your suggestion, we downgraded to 604 SP13 and issue was resolved.

Gurbir.

Hi Nani

Can you please check if you have maintained the CMS address for playing course. If not, Kindly

maintain it and select a default strategy under learning strategies using the SPRO settings and check.

Hi Chetan

Firstly thank you for your reply.

Now I just create a  course content by local PC, and tried to preview the content, so i think it doesn't need to link the CMS address. The content was published on local for preview, the following address like below.

http://127.0.0.1:53887/lms/mediator/courseview?sid=0&language=en

So I am not sure that more something need to configure in locally,

Best regards,

Nani
