Good! very thanks for your help

There is a little problem with the menu, if the words of the menu items are longer than the default (when I say default I mean English) it breaks to the next line - see the screenshot. I guess that it will be solved when the new CSS template is ready (please forgive me if I am wrong).

I have investigated, please remove from your override.css these:
remove !important from line 302,303,305
remove line 137,138,139

Ok, I understand.
I think you should do so:
- Disable 'Include Bootstrap CSS files'
- Remove your directive in override.css to resolve conflict with bootstrap CSS
- add at the start* of override.css the code attached to this post, this contains only bootstrap classes for tabs,button,dropdown button (used for privacy) and icons (used for privacy and some field).

* You can add everywhere you want, but the directive @import must be at the top of file

Do a backup of your override.css before.

Great!

I'll send you a PM about a special request. Well, I was testing the new layout, but at the same time I've added new fields and now I have error 500 in the frontend and in the backend i have a "String could not be parsed as XML".
I tried to identify what is the problem by turning on error logs and system debug with no luck,

Just to aknowledge you, this error has nothing to do with the CSS that you've sent, I am aware of it.

EDIT: It is just happening to the existent users, if I try to create a new one, there is no error. I didn't create any new user to test, just entered in NEW to see what would happen and cancelled without doing anything.

Sorry for that.

Ok, this is a bug. this heppen when there are char " in default value.

we will fix in next release
