Thank you @elliot!
I’m not good in java debugging, so I hope I did right…
I found an error when I open the edit category page:
Uncaught TypeError: Cannot call method ‘substr’ of undefined http://[mysite]/wp-admin/load-scripts.php?c=0&load%5B%5D=jquery-core,jquery-migrate,utils,wp-ajax-response,inline-edit-tax,plupload,plupload-html5,plupload-flash,plupload-silverlight,pl&load%5B%5D=upload-html4,json2&ver=3.8
I don’t know if it could be related with my issue. If not, please tell me where I should looking for accurately.
