Missing Add Media Buttons in Fedora Magazine WP Editor

Hi All, I have written my first article draft on Fedora Magazine, following the guidelines give here :http://fedoraproject.org/wiki/Magazine/Howtopost and with help from Paul W. Frields. However, while editing my article using either Visual or Text Wordpress editor, I am not getting the "Add Media", "Insert Slideshow" or "Add Contact Form" buttons. I tried clearing the cache, disable plugins, changing my system and browser language to en_US etc etc. I am running Fedora 22 Workstation x86_64 updated till today and Firefox 38.0.5 browser. Any ideas why this is happening? Paul confirmed he can see the buttons in Firefox on his PC so this could be something related to my PC or my account. Thanks. -- Regards, Sumit Bhardwaj
