I’m on version 3.1.1.4. I’ve got a mix of Articles and Issues that have been exported from other 3.1.1.4 instances. Some are importing fine and others I’m getting “the file could not be uploaded or revised” error messages.
When I had this previously with logos it’s because there were existing files of the same type in the relevant journal subfolder of Public. Once I removed those existing files the logos uploaded no problem. I’m not sure where exactly the articles/issues are supposed to end up in order to check if this is the same cause.
Sorry for not updating – everything is working ok now. I’m not 100% sure what the issue was it but it seemed one specific article had a problem that was preventing the whole issue being exported. By doing trial and error exports of the individual articles I was able to work around it.
