title: Can't change default logo
body: <p>I am trying to change logo in singnin logo and dashboard logo in Zabbix. I put two images inside directory /usr/share/zabbix/img  minilogo.png and biglogo.png</p>
  
  <p>And in both styles in /user/share/zabbix/styles blue-theme.css and dark-theme.css I have done changes: </p>
  
  <pre><code>.signin-logo {
    margin: 0 auto;
    margin-bottom: 21px;
    height: 30px;
    background: url(../img/biglogo.png) no-repeat 0; }
  
  .logo {
    float: left;
    display: block;
    width: 95px;
    height: 25px;
    background: url(../img/minilogo.png) no-repeat 0; }
  
  
  .browser-logo-chrome {
    background: url(../img/minilogo.png) no-repeat 0 0; }
  
  .browser-logo-ff {
    background: url(../img/minilogo.png) no-repeat; }
  
  .browser-logo-ie {
    background: url(../img/minilogo.png) no-repeat 0; }
  
  .browser-logo-opera {
    background: url(../img/minilogoo.png) no-repeat 0; }
  
  .browser-logo-safari {
    background: url(../img/minilogo.png) no-repeat 0; }
  </code></pre>
  
  <p>And in the end I run this command: systemctl restart apache2</p>
  
  <p>But when refresh browser, default logo of zabbix is still there, also when I login. Where is a problem?</p>
