Make sure the lines you add are processed as HTML and not PHP.

I tested on a new project (no Joomla, just an html and js file), and it works. So it may be because of Joomla but I can't find why.
Can anyone help me ?

What do you mean ? |

PHP often has a mixture of PHP code and raw HTML. The PHP gets processed on the server, the HTML on the client. It looks like the PHP is trying to process the JavaScript - which I’m not expecting to work.

But here is the start of my page `<?php defined('_JEXEC') or define('_JEXEC', 1); require_once(JPATH_BASE . DS . 'includes' . DS . 'defines.php'); use Anthias\Security; $mainframe = JFactory::getApplication('site'); $db = JFactory::getDbo(); ini_set('display_errors', 1); if (!Security::getInstance()->isLoggedIn()) { Is something wrong here ? |

Now that you’ve shown code - that looks ok.
Looking more closely at the error makes me wonder if something you’re touching (accessing the length property) doesn’t always have that property.
The test you ran without Joomla - did it have a doctype header? When Joomla generates the HTML, did it have a doctype header?
What I’m thinking is the browser is conditionally exposing a property or class based upon some logic - you’re not working on a level playing field.

I checked, and I have a 'DOCTYPE' header in both cases (I linked some images). So, this may not be the problem. But I'll show you my Joomla article's configuration below, can this be the problem ? Also, on Joomla's Administrator, it says i'm using an old version of PHP (PHP 7.4.33), do you think it may be the cause ? Test website : Joomla website : Maybe it's a conflict with an Joomla plug-in or extension, I'm searching the problem since yesterday and can't fin it. |

I identified a problem, in my Joomla template (rt_lexicon), there is that instruction So now I have to figure out why. |

Great progress. You might try moving your script line down the PHP file and see if that resolves the issue.

I don't understand, the line is in PHP, so that can't be the problem. |

Since the PHP code is effectively writing the HTML that will be sent to the browser that HTML could be invalid. I’m wondering if changing the location of the line you added (the line with the script tag including qrcode) can resolve the original issue?

Also, the website works very well, I just can't load html5-qrcode because it creates an error.

I work on a website made with Joomla.
