Data erased when I try to publish a new tab group

Hello all, since this morning on my blog when I try to use WP Tabs I have an issue, let me explain it.
When I create a new Tab Group and then click on publish, well nothing happen, it’s all delete I tried many times today and this evening by creating new, new tabs groups and still the datas are erased when I click on publish, so my question is, I have 7 of them who worked perfectly, is there some kind of limit ? I do stars bio and stuff like that as I took photo of them I create a news about them so i’ll need a lot more than 7 groups tabs as I have photographed more than 300 celebrities in official events.

Kind regards
