Hi @wodz82,
My best guess is that there is probably and additional plugin messing with rtMedia as we don’t encounter this issue with our demos. This is probably caused by some conflicting extra plugin or code snippet.
Could you deactivate all plugins that have not been installed with your theme during its setup and all existing custom PHP code snippets please? And then, could you confirm me that the issue is still persisting please?
Please also make that you have the latest theme version and that all recommended plugins are up-to-date. Finally, you could also consider clearing all activated caching system as well as your browser cache before investigating any further.
Thank you.
