Security token is missing
 

I am trying to add mp3 upload as attachment to my new forum but when I try to upload one, I get that Security token is missing message. I dont think that I did anything wrong.

I searched and have done this.... https://vborg.vbsupport.ru/showpost....6&postcount=14 and still I get the error.

Can anyone help?

If you've searched in the templates for it and can't find it, then it is probably either in a plugin or in the javascript for an older modification.

I can upload a small mp3, but not a normal sized, full length song. Im not sure what kind of plugin or javascript would possibly affect that.

You can try creating a totally default style and uploading the file and see if that makes a difference - Styles & Templates > Style Manager > Add New Style > no parent If that doesn't work, then I really don't know what else to suggest if you don't want to look through your addons.
