title: WordPress suddenly changed url addressing style from 'abc.net/home/... to abc.net/home-3/
body: <p>Please help with the issue on my WordPress site (I`ve Googled for nothing.</p>
  
  <p>My site has url structure "egf.ru/home/...", but suddenly all links become "egf.ru/home-3/.."</p>
  
  <p>It looks like the site decided to move permanently on his own will.</p>
  
  <p>I`m new to WordPress and failed to find out how to bring it back and what was the reason for that.</p>
  
  <p>The main trouble of this - SEO . Because now all previously valid indexed (egf.ru/home/... ) links become 404.</p>
  
  <p>And the next problem is that some articles still has inside of their text - links addressing to original egf.ru/home/.. - clicking them brings us to 404.</p>
  
  <p>And of course, if I would change that address manually in my browser from ../home/.. to ../home-3/.., it would immediately works perfect.</p>
  
  <p>So made a simple temporary "patch" of 302 redirect at <code>header.php</code></p>
  
  <p><strong>php pseudo</strong></p>
  
  <pre><code>if (('home/') inside $url) 
  {
      str_replace('..home..','..home-3..') 
      header(Location: ..home-3..)
      die:)
  }
  </code></pre>
  
  <p>to make all links valid.</p>
  
  <p>But this does not solve the problem globally.</p>
  
  <p>Please help me to bring it back to original route mode (../home/..). not as home-3.</p>
  
  <p>Ugh.</p>
