XF 2.2 Unformatted Toolbar inside post

[markoroots]

Hi everybody. Can anyone help me to understand what is the problem with my site?
I'm receiving this error:

    XF\CssRenderException: Error rendering template public:editor.less: ParseError: missing opening `{` in public:editor.less on line 5615, column 3 (on or near line 5615) src/XF/CssRenderException.php:89

}

Then I see that when I try to open a thread the tollbar inside the post is completly unformatted


I have make some modifications in the last days but I really don't know what I have done to make this.
Any idea?

Solved.
It was an apostrophe more in Settings->Typography->User Interface Font
