I can confirm, that it is Javascript error which happens only on the Edit Taxonomy Term. Now just have to find why it is happening. Seems like something with jQuery.
The error returned is “TypeError: a(…).attr(…) is undefined” and the link to file is:
load-scripts.php?c=1&load%5B%5D=jquery-core,jquery-migrate,utils,wp-ajax-response,inline-edit-tax,jquery-ui-core,jquery-ui-widget,jquery-ui-mouse,jquery-ui-sort&load%5B%5D=able,plupload,plupload-html5,plupload-flash,plupload-silverlight,plupload-html4,json2&ver=3.8
And for me it seems that it happens with the default WP installation. Just checked another site which has WP 3.8 and the same JS error occurs.
