Webstore Carousel Upload Error Message

Trying to upload some images to a carousel - images that are within the parameters of others I have successfully uploaded before - and they aren’t going through and I’m getting a red error message at the bottom right “Carousel Manager, Undefined”

Not sure what this means or what I need to change.

Hi Mary,

I noticed that you also opened a ticket related to this issue and got help there, often it’s better to resolve problems through tickets as we can share more information regarding the webstore.
For other readers: formatting of the imagefile matters when uploading it to the carousel. Not all formats are supported so it’s best to stick to PNG or JPG.

Image processing software can also alter how files behave when put through the frontend to upload. You can flatten the file and remove any added macros, filters etc. by saving it in paint for example.
