Sorry...
I paste an image but it did not appear
in the file there is this text..
<iframe id="contentframe" height="600px" width="100%" src="launch.php?id=82&triggerview=0" allow="microphone ; camera ; geolocation ; midi ; encrypted-media ; autoplay " allowfullscreen="1"></iframe>
I changed only the height. After that you have to save the file and restart apache server
