Hello,

I have a problem with my forum when someone search it on google. I added a new category for a game server and after that this happend (pic1), but without ".ro" it looks normal (pic2).

Any solution for this problem and maybe what it takes to look like this (pic3)?

That's normally controlled by your title meta tag which looks like it's

<title>WATF Romania</title>

Google may have picked it up as that at some point when it crawled your site and was redirected to http://furien.watf.ro/

I would resubmit to google the url: https://watf.ro/ 

You may also want to set up a 301 redirect for http://furien.watf.ro/ to redirect the requests to https://watf.ro/
