Hello!
I have one problem with location when someone try to add a listing.
Anything written at the location does not appear nothing!
You can test this at http://www.anuntbeton.ro/item/new

@ifrim
you have 2 javascript errors on your site, fix them or replace theme files with original:
Uncaught SyntaxError: Unexpected token <
new:959 Uncaught ReferenceError: ir_get_min_img is not defined
    at HTMLDocument.<anonymous> (new:959)
    at k (jquery.min.js:2)
    at Object.fireWith [as resolveWith] (jquery.min.js:2)
    at Function.ready (jquery.min.js:2)
    at HTMLDocument.D (jquery.min.js:2)

But I did not modify the original files of the theme...
How can i fix it?
Thank you!

There is modification with some script placed into body (tracking script, google adsense?)

But I did not modify the original files of the theme...
How can i fix it?
Thank you!

Try to OFF share  plugin from left side on your post page.

I found the problem...
The problem appear from the Image Required plugin bought from mb themes!! 
After i disable this plugin all works!
What can i do now? I bought a plugin from same provider that don't works...
But i really need this function for my website...

I would say you have older version of theme or plugin.

I bought plugin on 14 august 2017 and the theme on 1 september 2017, i lost an update for this elements?

@ifrim
I have PMed to you latest version of image required plugin, just to be sure.
But please open console of your browser and look for javascript errors (press F12).
Your google analytics code is invalid.

new:1066 Uncaught SyntaxError: Unexpected token <

      <script type="text/javascript">// <![CDATA[

<p>(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){</p>
<p>(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),</p>

<p>ga('send', 'pageview');</p>
<p> </p>
<p>
// ]]></script>  </div>
</div>


Fix that first.

So, i delete all analytics code from website and this plugin still does not work. I specify that I installed the last version, the one on the email

The location works if i disable the plugin

What plugin?

@ifrim
Data in your console referenced to problem with different script placed by you.

Ok! I will reinstall osclass from 0 to an subdomain and i will put just the theme and image required plugin to see what will happen!
