I’m having a problem with my Youtube player, which is displayed through an iFrame on my website. I keep getting an error message that says “You’re offline. Check your connection”. However, I know that my internet connection is stable and working perfectly fine. This always happens when I try to play a video on the player, and I can’t figure out what’s causing it.
Here’s the HTML code for the iFrame that displays the player:

I’ve tried a number of things to fix this issue, including:
1. Clearing my browser cache and cookies
2. Disabling any VPN or proxy connections
3. Checking if there are any ad blockers or browser extensions that might be interfering with the player
Despite these attempts, I still can’t get the player to work. Is there anything else I can try, or is this an issue with YouTube itself? Any help would be greatly appreciated.

    It seems like your issue might be related to your internet connection, as the error message suggests. My advice would be to try resetting your internet connection or trying a different network.

    I have experienced similar issues in the past, and whenever I encountered the “you’re offline” error message, it was almost always related to my internet connection. Sometimes simply resetting my router or switching to a different network solved the problem.

    If resetting your internet connection doesn’t work, you may want to clear your browser’s cache and cookies, or try using a different browser altogether. It’s possible that there’s a temporary issue with your browser that’s causing the problem.

    I hope this helps – good luck with your issue!

I am having some troubles with a JavaScript variable which appears to be undefined. I’ve searched everywhere and tried everything I could think of, but nothing seems to work.
Here’s a snippet of my code:

var phcat;
var myApp = angular.module('myApp', []);
myApp.controller('MyController', function ($scope, $http) {
$http.get('data.php').
success(function(data, status, headers, config) {
$scope.categories = data;
phcat = $scope.categories[0].id;
}).
error(function(data, status, headers, config) {
console.log(status);
});
});

As you can see, I am trying to assign a value to the variable “phcat” inside the success callback of an AJAX request. However, whenever I try to access “phcat” from another function, it turns out to be undefined. I tried moving around the variable declaration, using “var” and “let” keywords, and also initializing the variable to a default value, but with no luck. What am I doing wrong? How can I make “phcat” properly accessible outside the AJAX request? Any help would be appreciated.

    The error “libpng warning iccp known incorrect sRGB profile” usually occurs when an image has an incorrect profile. To resolve this issue, open the image using a photo editing software and make sure it is saved without any color profile or with a proper sRGB color profile.
    Sometimes this error is also generated because the image is missing a profile, so to fix this, you can set the color profile of your image before saving it. This can be done using a photo editing software or command-line tools like ImageMagick.
    In my personal experience, I had encountered this error while working on a web project. I had to make sure that all the images used on my website were optimized and saved with the correct color profile. This helps in reducing the page load time while maintaining the color quality of the images.
    To troubleshoot this error, it is also recommended to check if your code is properly handling the image files and loading them in the correct format. Sometimes, the issue may not be with the image itself but with the way it is being processed and loaded. By following these steps and practices, you can avoid this error and ensure that all the images on your website or application are displayed correctly.

I’m building a browser extension that uses the WebExtensions API.

I’m building a browser extension that uses the WebExtensions API. I have a content script with the following code:
“`javascript
browser.runtime.onMessage.addListener((message) => {
if (message.type === ‘get-browser’) {
const browserName = navigator.userAgent.includes(‘Firefox’) ? ‘Firefox’ : ‘Chrome’;
return Promise.resolve({ browser: browserName });
}
});
“`
When I try to load the extension in Firefox, I get an error in the console:
“`
Error: Error: browser.runtime.lastError: Could not establish connection. Receiving end does not exist.
“`
I’m not sure why this error is happening. I’ve looked at the documentation for `browser.runtime.sendMessage` and `browser.runtime.onMessage.addListener`, and it seems like my code should be correct. I’ve also searched on Google and Stack Overflow, but I can’t seem to find a solution.
One thing I noticed is that the error only occurs if I have the `permissions` key in my `manifest.json` file. If I remove it, the error goes away. But I need the `permissions` key to access the `tabs` API in my background script. I’m not sure if there’s a conflict between the two APIs, or if I’m doing something else wrong. Any help would be appreciated.

I’m having trouble with a JavaScript variable that is not defined. I’m working on a web application that tracks user scores for a multiple choice quiz. The quiz has multiple pages, and each page has a question with four options. The user selects the answer and clicks the “Next” button to go to the next question. Each question has a value associated with it, and I’m trying to add up the total score at the end of the quiz.
Here’s the code that I’m using to add up the score:

var score = 0;
for (var i = 1; i <= 10; i++) { var questionValue = document.getElementById("q" + i).value; score += questionValue; }
However, when I test the quiz and get to the last page, I get an error that says "ReferenceError: questionValue is not defined."
I've double-checked the IDs of the input elements and they match the IDs in the JavaScript code. I also checked the values of the input elements and they're numbers, so I'm not sure what's causing the error. Would appreciate any help or advice on how to fix this issue. Thanks in advance!

I’m building a website for my online store and I’m trying to display the date and time of purchases made by customers on the site. I’m using JavaScript to set the time and date format but I’m having issues displaying the time in the 12-hour format with AM/PM. Currently, the time is being displayed in the 24-hour format. Can anyone help me figure out what I’m doing wrong? Here’s the code I’m currently using:

var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
var dateTime = date+' '+time;
document.getElementById("order-time").innerHTML = dateTime;

I’ve tried using the %I and %p options to display the time in 12-hour format with AM/PM but it doesn’t seem to work. I’ve also tried changing the getHours() function to toLocaleTimeString("en-US", {hour: '2-digit', minute:'2-digit', hour12: true}) but that didn’t work either. Can anyone help me figure out what I’m doing wrong and how I can display the time in the desired format?
Another thing I noticed is that the seconds are being displayed even though they’re not necessary. How can I remove the seconds from the displayed time? I’ve searched online for solutions but I haven’t been able to find anything that solves my problem. I’m not very experienced with JavaScript so any help would be greatly appreciated. Thank you in advance!
