Good morning, in trying to attach a file to a post we can open the ‘File Uploader’ plugin box and add files by pressing the Add Files button or by drag and dropping. What isn’t working however is the ‘start upload’ button or indeed the – button allowing you to remove a file from the upload list.
Both WP, SP and the plugin are all at the most update versions. Many thanks for any help.
Edit: this console log shows the js error (“cannot call methods on button prior to initialization; attempted to call method ‘enable'”) that occurs from file plugload.full.min when any forum topic page is loaded. The same error is logged when the ‘minus’ button is clicked. We see no activity (and no error logged) when the Start Upload button is pressed.
