The source of this problem is tumblr.
But don't worry, I'll be back soon with something even better;.
It is therefore with great sadness that I announce that you are living the last moments of tumbex, it was a great adventure, and a big thank you to all those who have followed me during all this time! Using tumblr with an easy, clean and efficient interface was my goal.
It's unfortunate, I loved tumblr, that's why I created tumbex.
