I don't know if the problem is the Ajax, but I think so.
In plugin settings, the content from tabs do not open (see image: http://cl.ly/LTU2 ) and in the New Post page, the content from the metabox do not open either (see image: http://cl.ly/LSCb ).
I use the plugin from about ~1 month without problems, and today WHEN I UPDATE THE PLUGIN this happened.
P.s.: I tried change the browser, clear data, etc.
Thank you very much,
