Hi @chrispo,
I moved your post over here to a new post, since it could be better to look at it as a separate issue. Which version are you using(e.g 3.3.0-8)? Also, I noticed that you posted about this here: Ojs 3 image upload failed
It’s best not to post about the same issue twice, this helps keep the forum nice and tidy (see here: Forum Guidelines and Code of Conduct)
