Hello @Deepak_Kumar,
We suspect that one of the membership plugins installed on your website might have a conflict with rtMedia. Can you try disabling them one by one on a staging / testing site and verifying if the problem still comes up?
You can also refer to the following doc for conflict diagnosis-> https://rtmedia.io/docs/troubleshooting/conflict-diagnosis-guide-wordpress-plugins/
Let us know if you make any progress!
Regards,
Joel Abreo
