We are currently working on fine tuning and updating the dev backend of our CMS we're rolling out for a new site.
I was familiarizing myself with the new system and uploaded some images in error.
I then deleted said images using module Reports > Audit Files > Managed not Used.
Once I removed the file another user tried to upload the same file with a different name and we keep getting this error.
We've removed the file from the Database and the file server but still get the below error every time.
New to Drupal 8 and this forum... If you have solution or work around please let me know.
