"Unauthorized files have been removed" when trying to upload media in item authoring

I have an 3.1.0-sprint15 deployment that has been running for 2 years delivering the same test. however just yesterday i found out that i couldn't upload image/media when creating new item. when trying to upload i get an error message "Unauthorized files have been removed". also the old items that contains image cannot be rendered by QTIPreview (although, in the delivery they still viewable)


  • Hi there,

    Have you performed any updates on your server? could you provide a but more background on the environment you're running TAO on; operating system, infrastructure, etc.



  • hi mark, i think the problem may lie with unsupported php version. we tried several installation and it does seem using unsupported versions lead to that error
