Plugin not reacting to input

Hey.

The plugin was working just fine at Friday. After that 2 things I did that might’ve messed with the plugin was installing Hummingbird to optimize the website, and update last night’s elementor.

Now, when someone attaches a file and pressed “upload”, nothing happens. Progress bar doesn’t show up and the file isn’t being uploaded where it’s supposed to.

Shortcode:
[wordpress_file_upload uploadpatterns=”*.docx, .doc, .pdf*” maxsize=”3.5″ createpath=”true” forcefilename=”true” uploadtitle=”Upload životopisa” selectbutton=”Odaberi privitak” uploadbutton=”Uploadaj privitak” successmessage=”Privitak %filename% je uspješno uploadan” warningmessage=”Privitak %filename% je uspješno uploadan ali s upozorenjima” errormessage=”Privitak %filename% nije uploadan” waitmessage=”Privitak %filename% se trenutno uploada” notify=”true” notifyrecipients=”*private-email*” notifysubject=”Novi upload životopisa: %filename%” attachfile=”true”]

Can you help me fix this?
