title: Joomla! Too Many Redirects
body: <p>I'm trying to build a website (it's not my first time), using latest version of Joomla! (3.8.10), but I have a problem - tabs in the main menu don't work. When I try to go to other page, I have an error:</p>
  
  <pre><code>ERR_TOO_MANY_REDIRECTS
  </code></pre>
  
  <p>I almost solved this problem by changing:</p>
  
  <pre><code>$sef="1"
  </code></pre>
  
  <p>to</p>
  
  <pre><code>$sef="0"
  </code></pre>
  
  <p>in <code>configuration.php</code>, but it caused strangely long addresses.</p>
