Tumblr Problems

Hi,

I cannot share any page, post or product page in tumblr using this plugin.
It opens the sharer post but the posting button is greyout could you chek it please?
It happens in all my websites where I’m using your plugins since last year. All other sharing buttons work perfectly. My website is http://www.laplandinteractive.com
and this is the screenshot of the problem you see the “post” button is greyoff

2- is possible to have a sharing button for Ello?
Thank you.
Angelo
