I hope you are using this theme https://wordpress.org/themes/bluestreet/, I found it from the debug info which you shared with us. I checked with that theme and rtMedia plugin works fine without any issue.
Please update that theme with latest version 1.2.0.
As we are not able to reproduce your mentioned issue at our end. I suggest, once try rtMedia and that theme on fresh WordPress setup. Let us know it that works.
Alternatively, we may ask for login details for your website to debug further.
