title: Deprecated: strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior
body: <p>I have a problem with an old plugin installed on my Wordpress site. Since I updated my php to php 7.4, I am getting the message saying: &quot;<strong>Deprecated: strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior</strong>&quot;. The error is detected on line 454 of <strong>UpdateChecker.php</strong> file, which is the following:</p>
  <p><code>$cachedResult = (strpos($pluginPath, $muPluginDir) === 0);</code></p>
  <p>Could anyone please help me to solve the issue? I would really appreciate!</p>
  <p>Thanks in advance</p>
  <p>Cheers</p>
