I get an error 200 when I try to create or edit a MediaSource. I notice that the dropdown for Source Type is displaying a path (MODX\Revolution\Sources\modFileMediaSource).
The media sources do work and function as planned. So what ever the error is, it is not preventing correct functionality
Step to reproduce
Editing or creating a media source triggers the error
Displays error 200 error dialog but Media Sources do function correctly
MODX 3.0.3 on a shared hosting environment. Installed using Softaculous. I think (not 100% sure) the original install was 3.0.2 and then upgraded to 3.0.3 using Softaculous. Since 200 errors are typically permission issues, I checked to see if the user is a sudo super admin (yes). The user has 187 permissions (I have not worked with ACLs in Modx3.x, only 2.8.x), so I am not sure if any permissions were added in 3.0.3 and I need to set them.
