Menu gone, only can see a number

Hi all, i’m having this issue. The site was working just fine. I set up a reCaptcha for my contact form, after this the whole menu disappeared and i can only see them number “6” to the far left.
How could i fix this? any ideas?
when i inspect the code, where the menu should be all i get is:

<div class=”header-top clr”>

<div id=”site-header-inner” class=”clr”>

<div class=”left clr”>

<div class=”inner”>

<div id=”site-navigation-wrap” class=”clr”>

306

</div><!– #site-navigation-wrap –>

Hope anyone can help, thanks
