 * Hi,
 * The plugin seems to be breaking MP4 video file upload functionality. I tested
   on various environments, but the result is always the same. Deactivating the 
   plugin resumes normal behaviour.
 * The error is:
   _Unexpected response from the server. The file may have been uploaded
   successfully. Check in the Media Library or reload the page._
 * The file actually does get uploaded to the server, but is not visible in media
   library even after reloading the page.
 * Are you able to replicate this issue on your end?
 * Best,

 * Hi dg,
 * No, sorry, we are not able to replicate the issue on our end. From our side, 
   everything works well. To help you troubleshoot the issue, it would be good if
   you could…
    - check if the issue happens with all MP4 videos,
    - check if the issue happens with a test site on [https://tastewp.com/](https://tastewp.com/)(
      for example),
    - check if the issue happens on all internet connections,
    - check if the issue happens on all devices,
    - check if the issue happens on all browsers,
    - and check if the issue happens with all plugins deactivated (except ours, 
      of course).
 * That should point you to where you should look at.
 * Have a nice Sunday!
