When writing/editing the post/page, take a look at the Publish box to the right, then the Status field highlighted in this screenshot: http://d.pr/i/nFio/1j1Mx90L
Click the Edit link next to it, select Published from the menu that appears, and click Ok: http://d.pr/i/17ltw/36Bc3NNU
Then you’ll be able to Publish your posts rather than just save it as a Draft.
If you are only able to save drafts (if you cannot change that status), then you may only be a Contributor on the site, and you’ll need to contact an Author or higher to publish the content: https://codex.wordpress.org/Roles_and_Capabilities#Capability_vs._Role_Table
Seriously? š I am a heavy WP user. I think I know the difference between “Publish” and “Save Draft”. But thank you for trying to be helpful.
The button says (in Romanian though): “Publica” = “Publish”.
I am having problems with other things, too, not only publishing the article. It doesn’t remember the featured image I am setting and the tags I’m adding to an article.
Interesting, sounds like quite a bit is going wrong then. I should have grasped it wasn’t an account level issue based on your ability to disable plugins and switch themes, sorry about that.
So, it’s not plugins, themes, or core files, which leaves one more third-party element to rule-out: the browser.
First, please make sure that your browser is up to date by visiting https://whatbrowser.org/
If it is not, please try updating your browser or switching to a different browser.
If it is, please do these two things:
1. Try clearing your browser’s cache and cookies.
2. Try with all browser extensions or add-ons temporarily disabled.
Please let us know how each step goes for you, and which browser (and version of) you’re using if you’re still having trouble.

I cleared the cache and cookies + disabled all browser extensions or add-ons -> same result.
Firefox 38 or IE 11 -> same result :/
I also tried it with the default theme and all plugins deactivated after clearing browser cache and cookies. No luck :/
So, it looks like last time you had something similarly strange happen, mod_security was the likely culprit: https://wordpress.org/support/topic/post-changes-arent-saved/
Any change with mod_security disabled?
It isn’t enabled, I remembered that post/problem, too. Then I went and checked it before I came here to post. It was not the case there and it isn’t here, too.

Anything in your error logs, or any PHP errors from the actions that cause the issue?
https://codex.wordpress.org/Debugging_in_WordPress
How about errors in the JavaScript console?
https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors
Featured Image + JS console + I deactivated a plugin that was giving a php warning.
At this point I had
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', true );
error_reporting(E_ALL);
ini_set("display_errors", 1);
define('SCRIPT_DEBUG', true);
in my wp-config.php
Setting Featured Image and updating:

But Featured Image is gone after update:

I have no error log on the server either .. this is so weird.
Hm, language-related issues are rare, but do you have any trouble if you switch over to English?
What version of PHP is the server running?
Is the server Apache, Nginx, or IIS?
– PHP Version 5.4.45
– Apache 2
I’ve set the language to English (United States) with no problem. Language is now English but errors are the same.
Any chance you could upgrade to PHP 5.6.x or 7.0.x?
The 5.4 branch reached end of life last year: http://php.net/eol.php
Not in my power unfortunately, I only own a VPN and not a dedicated server. But the good news is they are preparing to upgrade to 7 soon.
Are there any other security bits in the process, like Cloudflare, Sucuri, etc?
