Cannot save nodes

Hi,

I add the same errors presented here : https://www.drupal.org/node/2717455#comment-11147303
=> impossible to save a node with boostrap module, it redirects to the node edit form without any error message.

My install is all fresh, but I've installed boostrap module on a very different server and it works, so I guess this error could be done to server configuration but I have no clue what it can be.

Any help appreciated!
