  • Attempt to upload a simple jpg image in either front or back-end.
  • Receive error message: 'Illegal or invalid mime type detected.'
  • Tried on a number of sites - same issue.
  • Switched editor to TinyMCE and it works fine.

This has only been reported to me from my users since the Joomla 3.7.1 update.

Both Ark Editor and Ark Media are the latest available downloads.

Hi aiswebadmin,

Thank you for reporting this, we are aware of this issue and will be working to release a fix for this soon.

Until then please apply the following workaround:

  • Go to Ark Media's configuration page.
  • Go to the File Info tab.
  • Select the Custom Allowed File Types and add the following custom file types to fix the authentication error:
    • image/jpeg, jpeg, Images.
    • application/octet-stream, mp3, Audios.

Hopefully that will work till we can get a fix out for you.
