An item with the same key has already been added.

Is there a way i can fix this? Do i need to flush a DB table? Delete a chach file? if so which ones?
Yeh i created a seperate Media Type to have a Image Cropper as the Upload, therefore you would crop the image at the Media section rather than a property editor.
Seems setting UmbracoFile borked it. I couldnt fix it, or didnt have time to try so i just created a fresh install and transfered everything over.
Would be nice to fina out how to actually fix that but looking in the DB i couldnt see what to delete.

Hi it looks like you have got some custom stuff there?
Go into Umbraco where you define custom properties for the media items.
You have a duplicate property i would expect called AdditionalThumbSize
Remove the duplicate and you will be all set to go.
Sorry i cannot remember how to get there of the top my head, but pretty sure its in the setting section / media.
