Hello,

Some users from my forum have access to reply to a topic but the reply box is not extending. Only some users have this bug.

Here is a picture with the bug after click on reply:

What's the problem?

I've tried to change theme, uninstall plugins and applications and nothing works.

No one can tell from just a screenshot. 

It can just be a cache problem. Forcing a reload or clearing the browser cache can resolve it. 
The other typical cause: a JavaScript problem. Either a conflict on your site (e.g. with third-partly themes/plugins/customizations) or a problem on the users end, e.g. browser plugins which interfere or block JavaScript. 

It’s hard to resolve without more information from the user (e.g.what their browser’s error console says) or access to their computers.

You don't have the forum in developing mode, have you?
If so, you can check that in constants.php

define( 'IN_DEV', TRUE );

I have that with my dev forum, once this is set, reply boxes don't appear.

Looks like this error is in the console for users that can't reply:

ckeditor.js?v=f062ba6849:241 Uncaught Error: [CKEDITOR.resourceManager.load] Resource name "ipslink" was not found at "//forum.bigzone.ro/applications/core/interface/ckeditor/ckeditor/plugins/ipslink/plugin.js?t=H959".
    at window.CKEDITOR.window.CKEDITOR.dom.CKEDITOR.resourceManager.<anonymous> (ckeditor.js?v=f062ba6849:241)

    at HTMLScriptElement.CKEDITOR.env.ie.f.$.onerror (ckeditor.js?v=f062ba6849:237)

But this error is only for a few users.

And if I try to access forum.bigzone.ro/applications/core/interface/ckeditor/ckeditor/plugins/ipslink/plugin.js?t=H959 from that users's pc it's showing 403 error, but I don't get that error and it's working fine for me...

I've tried to access /applications/core/interface/ckeditor/ckeditor/plugins/ipslink/plugin.js?t=H959 and I get 403 error and if I try to access /applications/core/interface/ckeditor/ckeditor/plugins/ipslink/plugin.js without ?t=H959 it's show me the code.

With that error message, there might be a good chance to get that resolved through a support ticket. :-)

Also, standard other reply is make sure you aren’t using cloudflare rocket loader or any other JavaScript minify or speed type plugins.
