Hi Randy!
Thanks for getting in touch with us. Let me try to help you with this conflict.
I’m not familiar with the Mediacast plugin and could not find it the WordPress repository. Could you please let me know more about the plugin and the issue you are having?
Also, could you please enable WP_DEBUG and WP_DEBUG_LOG ? This will create a debug.log file inside the /wp-content directory.
After that, try reproducing the issue a few times, so that in case there is an error, it will be saved into the debug.log file. Please share that log file with us so we can see if any problem from there.
Thanks,
Victor
