While I was able to download an MP3 for a video, I was immediately given a popup to a porn site.
Not cool.

UPDATE Oct 10-22:
You *MUST* use a strict pop up blocker add on and deny the page from opening any pop up windows. When clicking the "Download MP3" button, you will get a pop up. Also the first click after refreshing the page, and every other click with a gap of 10 seconds anywhere on the page. These pages will be everything from "adult content" pages to fishy/phishy add-on advertisements.
Not every click on the green button will work to start the download either. You may need to refresh the page.

Update: Is working again. Simply click the "MP3" button next to the view count on the video, click your desired bitrate on the next window, and done!

Hasn't worked for a little while now. Downloads a 0KB file. Last checked: 08-24-21, 10P GMT

Youtubes audio quality is 128 kbps ACC. Downloading at 320 kbps results with an unnecessary too large file. Some experts state that not only it doesn’t improve the quality it even deteriorates it. It would have been an excellent add on if it had several bit rate choices 128/256.

I do like this add-on as it's very easy to use and quickly converts the audio track for download. I'm only giving two stars since it recently has begun to open a new tab every time prompting me to download other software, upgrade my Flash, and other irritating spam. Seems like either this add-on has been hacked, filled with malware, or worse. It's too bad since I really enjoyed usng it.

It worked great for a short time, but now it's not working, and I can't find a troubleshooter to fix it.

The past couple of days some videos seem to convert but when the download button is clicked the following page appears:
Fatal error: Uncaught Error: Call to a member function render() on null in /www/wwwroot/ytapivmp3.com/lib/Core.php:60 Stack trace: #0 /www/wwwroot/ytapivmp3.com/Routes.php(156): YouTubeConverterPro\lib\Core->download('zFFa1YHxwy8', 'mp3', '320') #1 [internal function]: {closure}('zFFa1YHxwy8', 'mp3', '320', '1591713419', 'a1a205d715038e0...') #2 /www/wwwroot/ytapivmp3.com/vendor/bramus/router/src/Bramus/Router/Router.php(379): call_user_func_array(Object(Closure), Array) #3 /www/wwwroot/ytapivmp3.com/vendor/bramus/router/src/Bramus/Router/Router.php(361): Bramus\Router\Router->invoke(Object(Closure), Array) #4 /www/wwwroot/ytapivmp3.com/vendor/bramus/router/src/Bramus/Router/Router.php(287): Bramus\Router\Router->handle(Array, true) #5 /www/wwwroot/ytapivmp3.com/index.php(12): Bramus\Router\Router->run() #6 {main} thrown in /www/wwwroot/ytapivmp3.com/lib/Core.php on line 60
Most videos convert and d/l great, but something is causing this error . Where or what is the problem here?
