I have a page using the attachments macro to upload some files, it allowed me to upload a few, but it wont allow me to upload the rest.
The file sizes are a tiny 24kb, and there's no special characters in the file names and I have tried with multiple file types.
When I attempt to drag the file into the drag and drop box, the following error with no text pops up at the top:

When I click on browse for files and select the file and upload it, it appears to upload and the page refreshes, but the file was not uploaded... with no error message.
Any help would be great.
