I’m having an issue with the multi-file upload not working. Neither the ‘select files’ button or the drag and drop area is working. Test site is at Medico Legal | Litfield House Medical Centre
Edit: There is no console error log or any other error being generated.
Does it work on the Form preview page? I’ll suggest you run a Theme/Plugin conflict test to check if this is a conflict-related issue and hopefully narrow it down to the offending plugin.
